This article describes the application of a systematic approach to an electric power technology engineering (EPTE) program that ensured highquality (Accreditation Board for Engineering and Technology -ABET) preparation. It describes how the Electrical Engineering Department at Palestine Polytechnic University (PPU), in Palestine, prepared for the EPTE program by defining and reviewing objectives and outcomes through a well-designed quality improvement process, and then implementing these evaluation results to develop the program. By obtaining results from courses delivered in two consecutive semesters, which could be more widened to a cycle of two consecutive academic years, it was possible to identify all student outcomes (SOs) with performances that either improved or deteriorated against a set threshold level of 80%. The final scores showed a mixed performance. While some SOs fell shortly below the set 80% threshold to an average level of 70%, others either met or exceeded threshold expectations. A deterioration in student outcome SO1 score related to ability of students to formulate and solve complex engineering problems. The SO2 score would require the laboratory and theoretical instructors to provide more discussion lectures and homework, in regard to circuit, system or process design, implementation and verification. The SO5 score showed that students needed to function more effectively as a team, while SO6 score indicated that students needed to improve their skills in experimentation, interpretation and analysis of data. The good scores; SO3, SO4 and SO7 related to ability of students to communicate effectively, recognize professional ethics and acquire and apply new knowledge.

With the introduction of emission standards automobile manufacturers have been using electronic control units (ECUs) to affect dynamic engine control to achieve higher efficiency. This trend has been expanded to all other facets of the automobile including in-car entertainment. Further, all these modules are tied together through a common communicating medium so that they can be controlled by a single input from the user or another module. However with usage, the components of the modules wear out or malfunction. While the offending module may be isolated using On-board Diagnostics, the exact cause of the malfunction is not easy to isolate without specialized testing; hence, the module is usually replaced at considerable cost to the user/original equipment manufacturer (OEM). These units may be effectively remanufactured at a fraction of the cost of a new module by replacing the failed electronic components. To determine the exact point of failure and ensure they are fully functiona...

In this paper, a proposed methodology to identify the substrate coupling effects in smart power integrated circuits is presented. This methodology is based on a tool called AUTOMICS to extract substrate parasitic network. This network comprises diodes and resistors that are able to maintain the continuity of minority carrier concentration. The contribution of minority carriers in the substrate noise is significant in high-voltage and high temperature applications. The proposed methodology along with conventional latch-up problem identification for a test case automotive chip AUTOCHIP1 are presented. The time of the proposed methodology is significantly shorter than the conventional one. The proposed methodology could significantly shorten the time-to-market and ameliorate the robustness of the design.

There are various aspects to Internet of Things security, such as guaranteeing the safety of both the devices and the Internet of Things networks to which they connect. Many other types of equipment, including industrial robots, smart grids, construction automation systems, entertainment gadgets, and many more, are included in this, despite the fact that they were not designed with network security in mind. When it comes to securing systems, networks, and data, IoT device security must be able to resist a wide range of IoT security assaults. One of the most important issues in the field of data security is the creation of intrusion detection systems (IDSs) for the Internet of Things. Client devices (edge devices) in Federated Learning utilize local data to train the machine learning model, and then send the updated model parameters to a cloud server so that they may be aggregated (rather than raw data).This paper proposes a machine learning system that employs federated learning to detect intrusions in the IoT. The FedAVG algorithm is employed to aggregate models. Models are trained locally by nodes. The models are trained and validated using machine learning methods, including Random Forest, ID3, and Support Vector Machine. The NSL KDD data set is employed to undertake experiments.

For cooling electronic systems new techniques are invented. Cold plate is liquid cooling system used in electronic components. In present work, the modification is done in design of cold plate to reduce its cost and also to increase the heat dissipation rate. Water at various flow rates is supplied for given power inputs and heat removing capacity of each flow rate at that particular heat load is calculated. It is found that water is best working fluid for all flow rates. Methanol and acetone are best suited for high mass flow rates. The cold plate is used to provide a "cold wall" to which individual electronic components are mounted. The design and performance evaluation of a cold plate follows a prescribed procedure that depends on the heat loading and whether the heat loading is on one or two sides of the cold plate. Due to transmission of applied current and voltage sometimes the temperature of the circuit plate goes increasing. This temperature limits the electronic operation. Thus it is necessary to control such temperature, in order to maintain speed of electronic devices.

Classroom management is an important factor in creating a fun learning process. Each process of learning has to get attention and preparation so that the whole series of learning activities organized to improve student competence. Total quality management (TQM) is a management system that demands to manage quality in every process. In the industrial sector, TQM in is used to manage each process in a series of quality product results. If in the learning process, TQM can be applied as an effort to create graduates with high competence. In this study, an analysis of handout characteristics before applying TQM is applied. Standard teaching materials both theory and practicum applied is planned based on the indicator of learning achievement that would be obtained. Furthermore, the process of preparing the teaching materials should also be followed by the analysis of teaching materials, so that when the remedial students get additional material to be able to complete each sub subject of the course. This research uses research and development method with field study and observation. The result of the development of teaching materials both practicum and theory is needed as an effort to update the study in pursuit of the achievement of the competence of graduates.

The explosive growth of the Internet has brought many good things: electronic commerce, easy access to vast stores of reference material, collaborative computing, e-mail, and new avenues for advertising and information distribution, to name a few. As with most technological advances, there is also a dark side: Some people are sending attachments through emails like spam mails and some fraud images .In this project we check the mail before sending it to the receiver mail id for the fraud images using “Skin Detection Algorithm” and also identify the spam mails. If any fraud images and spam mails are identified then the IP address and physical location of that sender is identified by a third party application. This ethical hacking technique is effectively used for identifying the location of the spam mail. After identifying the sender of the mail, discard the mail and send some warning message to that sender mail id. If that mail doesn‟t contain any spam files or abusive images, send i...

Razvoj pomoćnih sustava za usporavanje Tijekom 20. stoljeća došlo je do masovne proizvodnje autobusa, kamiona i ostalih teških gospodarskih vozila. S obzirom na njihovu veliku masu i opterećenost pri vožnji u operacijama kočenja dolazi do trošenja kočničkih obloga velikih razmjera. Sa svrhom rješavanja ovog problema, kao i povećanja sigurnosti vožnje razvijeni su pomoćni sustavi za usporavanje, tzv. retarderi. Sve je počelo još davne 1960. godine kada je Voith napravio prvi hidrodinamički retarder koji je našao primjenu u lokomotivama u Sjedinjenim Američkim Državama. Nakon osam godina razvoja retarder je 1968. ugrađen u prvi autobus i tako je Voith počeo nuditi pomoćne sustave za kočenje cestovnih vozila. Od tada je došlo do prave revolucije u ugradnji i korištenju ovog izuma. ZF Friedrichshafen AG je od 1975. godine počeo spajati svoje mjenjače s Voithovim retarderima. Slijede godine razvoja manjih retardera za gospodarska vozila srednje klase, nastaju sekundarni retarderi, a 2002. godine nastaje primarni retarder na vodu tzv. Aquatarder. Retarderi su rezultirali stvarnim prednostima jer ne samo da sigurno usporavaju vozilo nego smanjuju troškove održavanja vozila, produženo je vrijeme servisa, povećani su kapacitet tereta i prosječna brzina, što su velike uštede za vozače i prijevozne tvrtke. Retardere u svoje autobuse, kamione i ostala gospodarska vozila ugrađuju tvrtke kao što su MAN, DaimlerChrysler, Volvo i mnogi drugi. Voithovi sekundarni retarderi smješteni su iza motora, spojke i mjenjačke kutije. Zbog ovakvog rasporeda ovaj retarder se naziva sekundarni. Dva su načina ugradnje retardera tzv. "Offline" i "Inline". U "Offline" načinu ugradnje retarder je pričvršćen uz mjenjačku kutiju, a brzina raste u odnosu prema brzini pogonske osovine, ovisno o prijenosnom omjeru. Izrazito je kompaktan i omogućava veliku snagu kočenja čak i pri malim brzinama. Slika 1: "Offline" U "Inline" slučaju, retarder je ugrađen u cjelinu mjenjačke kutije (slika 2-1) ili izravno u kardansku osovinu vozila tako da je spojen s dva univerzalna zglobna vratila u mjenjačku kutiju i stražnju osovinu (slika 2-2).

The increasing complexity of automotive electronics has put considerable pressure on automotive communication networking to accommodate in-vehicle information flows. The use of power lines has been a promising alternative to in-vehicle communications because of elimination of extra data cables. In this paper, we focus on the latest HomePlug Green PHY (HPGP) which has been promoted by major automotive manufacturers for green communications with electric vehicles, and study its worst-case access delay performance in supporting delaycritical in-vehicle applications using both theoretical analysis and the simulation. Specifically, we apply Network Calculus as a deterministic modeling approach to evaluate the worst delay and further verify its performance using the OMNeT++ simulation. Evaluation results are also supplemented to compare with legacy methods and provide useful guidelines for developing HPGP based vehicular power line communication systems.

The use of electronic systems in automotive applications is characterized by special requirements concerning surrounding conditions, e.g. near the engine or breaks, and reliability demands. More and more piezoceramic sensors and actuators become common in such systems. Especially piezoceramic actuators are characterized by high power, low volume, fast mechanical response to an electrical pulse and a high variety of possible geometries. One application of such actuators is to drive fuel injection valves in internal combustion engines like diesel engines or petrol engines. The goal of the project group during the past years was the development and evaluation of a safe and reliable connecting and packaging technology for piezoceramic actuators in this field of application. Our paper presents, based on the general demands to the actuators and so to the technologies, the investigations that have been made, the realized tests (reliability test, endurance run), some results of destructive and non-destructive diagnostics (cross sections, x-ray) to assess the interconnections and the general results of the project.

Automotive embedded systems are widely used in modern vehicles such as cars, aircrafts and so on. However, modeling and evaluation of these systems is very challenging because time-to-market is very short and vehicles use very different platforms with various sensors, operating systems and embedded software modules. In this paper, we propose a TrueTime-based networked automotive platform (TrueFlex) which enables modeling and simulation of processing units, operating system kernels, communication bus and sensors/actuators in realtime or non-realtime automotive systems. This platform is easily upgradeable and provides different abstraction levels for modeling of automotive embedded systems with very informative reports and graphs. This platform is implemented and evaluated in this paper to show its very useful capabilities for automotive electronic designers.

Since the majority of the innovative trends in automotive industry today are based in advanced electronics technology, mastering the EMI (Electromagnetic Interference) between embedded electronic subsystem and the EMC (Electromagnetic Compatibility) features of a vehicle in its early design phase becomes one of the crucial technical challenges faced by all automotive manufacturers. Even if all electronic subsystems in a vehicle are validated under the EMC standards, the integration between them may create numerous points of potential hazards that affects the total electromagnetic behavior of the entire system, hazards that can be detected only once the first complete prototype is available, and whose resolution at this phase of the process is very time consuming and expensive. This paper presents the state of the art regarding electromagnetic numerical analysis using Ansoft HFSS (High Frequency Structure Simulator) tool and a parallel HPC (High Performance Computing) consisting of numerous computer nodes connected to a network. An application of this approach to a vehicle modeling is presented. Adaptations to CAD (Computer Aided Design) models are proposed in order to improve CAE (Computer Aided Engineering) analysis and save computer effort with the objective to reach a correct level of industrial efficiency. EMI between subsystems are investigated using field solvers and a SI (Signal Integrity) analysis is performed in a wiring harness transmitting a random CAN J1939 standard signal. A complete analysis on EMI and EMC properties is performed, and a conclusion concerning the practical use of numerical simulation at early stages of the vehicle design is proposed.

Automotive engine functions are entirely dependent on installed sensors performance. Any malfunction in the sensors can lead to degraded engine efficiency. This manuscript presents a novel scheme to devise virtual sensors for health monitoring of engine air intake path sensors. The proposed scheme assists in: Sensing of critical immeasurable parameters like Volumetric and Combustion efficiency, development of Virtual Sensor from manifold pressure dynamics for rotational speed and vice versa, Health Monitoring of the manifold pressure and crankshaft sensor. For the suggested scheme, two robust second-order sliding mode observers are employed that require two state mean value engine model based on inlet manifold pressure and rotational speed dynamics. The proposed methodology has the potential of online implementation on any automotive engine after minor tuning. In this paper, the procedure is customized for 1.3 L gasoline engine sensors: Manifold Pressure and Crankshaft sensor. The implementation results demonstrate that all the three mentioned tasks are accomplished efficiently.

It is seen that the number of Electronic Control Units (ECUs) in the automotive has grown significantly in recent years. In today's luxury cars, up to 2500 signals are exchanged by up to 70-80 ECUs. The number communication channels implement required realize such systems is about n2, here n is the number of ECUs in the automobile. This complexity requires the use of communication networks between them and to manage the functionality of these ECUs the Real-Time Operating Systems (RTOS) is used. This real world scenario has motivated us to give the hands on experience to students by introducing integrated course projects, which includes the use of Real-Time Operating Systems (RTOS) in automotive embedded systems. This activity also involves creating an industry like environment for execution of the project. Deployment of more advanced control strategies and integration of sub modules were the major technical outcomes of the activity.

Modern Electric Vehicles (EVs) require high power and high efficient powertrains to extend their power range. A key element of the electric powertrain is its drive with an electric machine controlled by a traction inverter. A cooling system dissipates heat generated due to the losses in this inverter and keeps its temperature within limits, i.e. below the operational maximum value. Indirect cooling systems are often the preferred solution due to their easy implementation and robust separation of the electric/electronic parts and the coolant circuit. Indirect cooling comes with additional surface interfaces, hence thermal barriers and increased thermal resistance for the losses' heat flow path. One way to increase the system's heat transfer coefficient is by implementing power electronics with dual-sided cooling (DSC) solutions and by enhancing surface structures for the cold plates. Manufacturing complex cold plate solutions with internal surfaceenhancing structures by way of classical techniques (e.g. aluminum extrusion with CNC machining) can be difficult, costly, or even not possible. Sealed one-piece solutions are preferred, without the need to weld parts or use screws, glue, gaskets, etc. 3D metal printing allows to manufacture of a one-unit compact, light, and reliable cold plate. This study shows the advantages and limitations of a 3D metal-printed inverter cold plate by presenting the microchannel design, numerical thermal simulations, and experimental results for the liquid cooled DSC SiC and Si inverters. This work explores the compatible use of 3D metal printing solutions, which will aid the development of modern high-power density EVs.

Power range, efficiency, energy consumption of EVs are determined by the components of the powertrain, which includes an electric motor, a high voltage battery along with a power electronics interface: an onboard charger, a DC/DC converter and an inverter (Figure 1) [7]. The power electronics components are responsible for controlling the flow of electrical power in an EV, directing it in both directions (motor mode or generation mode) between the battery and the electric motor, which serves as the propulsion system for the vehicle.

Bluetooth is an emerging technology for short-range wireless communication. It is designed to transfer data over Asynchronous Connectionless (ACL) links and voice over Synchronous Connection-Oriented (SCO) links. SCO packets are sent at regular intervals and are never retransmitted, while ACL packets are retransmitted in case of error. In this paper we have investigated speech recognition performance for voice transferred over ACL and SCO links at various channel qualities. Our experiments have shown that channel quality has severe impact on speech recognition performance for voice carried over SCO. This justifies the use of ACL links for voice transmissions in speech recognition applications.

Consumer electronics increasingly find their way into cars and are often portrayed as unwanted distractions. As part of our endeavour to capitalise on these technologies as safety tools rather than safety threats, we suggest to use smartphones, head-up displays, vehicle interfaces, and other digital gadgets: a) as readily available and lightweight sensing devices, and b) as platforms for engaging interventions that provide safe stimuli in realtime while driving. In our effort to make safe driving behaviours more fun, we explore ways to apply gamification to driving. In this paper, we illustrate the need for a careful balance between fun and safety and reveal ethical issues that arise when introducing new technology interventions into this complex and safetycritical design space.

This paper addresses the behavior of low voltage MOSFETs uLnder breakdown avalanche operation. The phenomena leading to avalanche operation of the MOSFET transistors in automotive applications are first presented. Then, after a brief description of the model and of the experimental identification of its parameters, electrothermal simulations are performed. A special focus is given to the curmrnt balance between paralleled MOSFETs, because in this case breakdown voltage mismatches are a well-known reliability issue. These simulations demonstrate the influence of the specific avalanche path resistance on current sharing. Calculations perfonned using the proposed model give results far less pessimistic (lower temperature rise on the most stressed transistor) than classical temperaturedependant-only avalanche models. This avoids expensive specifications narrowing when designing for mass-market applications (where wide manufacturing dispersions occur).

Nowadays remote access to systems in the instrumentation and measurement fields is both a reality and a challenge. There is a growing interest in replacing manual actions performed on site by remote actions carried out from anywhere around the world. To do that, besides the availability of suitable communication networks, it is necessary for the elements involved in the network to recognize each other, this latter task perhaps being the most complex one of the two. Integrating different hardware/software from different manufacturers into a single system with controlled remote access is not a trivial task. This paper presents a fully integrated open solution for the operation of pilot plants (scaled down, laboratory level industrial plants operated in university and other environments) using open access hardware/software on public networks. The proposed solution is independent of the nature of the pilot plant and its elements and can therefore be considered standard. In order to illustrate the capabilities of the proposed solution, two different types of pilot plant are presented.

Inductive Power Transfer (IPT) is by far the most popular method to transfer energy wirelessly and has attracted considerable attention in recent times. The Wireless Power Consortium (WPC) has developed a standard (Qi) for low power consumer electronics, whereas, the Society of Automotive Engineers (SAE) is working on a standard (J2954) to charge Electric Vehicles (EVs) wirelessly. SAE's current efforts are only focused on transferring power to the vehicles at rest (static), whereas no work has been done so far on developing the standards for transferring power to the vehicles on the move (dynamic). This paper presents the magnetic design of an IPT system for a dynamic EV charging application, to continuously deliver a power of 15kW to an EV, along the direction of travel within the lateral misalignment of ±200mm. The experimental validation of system operation, however, was conducted at 5kW. The design aims at distributing the cost and complexity of the system between the primary and secondary side, while achieving a smooth power transfer profile. In addition, the system is designed to exploit the shielding effect provided by the vehicle, as the field generating components of the system are covered by the vehicle body under all operating conditions.

In the project IRMA-EU (IRMA: integrated resonant accelerometer microsystem for automotive applications), a project sponsored by the European Commision under ESPRIT, SensoNor and project partners Autoliv and SINTEF are developing a resonant-structure two-chip accelerometer silicon microsystem for automotive applications, the SA30 Crash Sensor for front impacts, with range f 50g. The project is focusing on the development of key process technologies, product designs and manufacture of functional prototypes. The IRMA project is coordinated with other activities performed by the partners to cover all aspects of research and technology development as well as establishment of high-volume production capabilities needed for successful product innovation of this new generation of crash sensors. The sensing principle is an acceleration-sensitive resonant structure, with an ASIC for resonance control and signal conditioning. Prototypes in silicon of both the sensor chip and the ASIC chip have confirmed the feasibility of the concept. Ramp up to high-volume production will be started as soon as fully functional microsystems are demonstrated.
