The method adopted is computer vision and deep learning paired with an internet of thing (IOT) system that is capable of segregating municipal waste into Organic and Recyclable waste. Eliminating manual segregation in the process of waste management significantly reduces the risk to the health of municipal workers by preventing the contraction as well as the spread of transmissible diseases. Automation will also increase the speed while significantly reducing the cost of the waste segregation process. This study was conducted in order to ideate and bring to life innovative and sustainable ideas for effective waste management systems with little to no human intervention.

Although the terms e-marketing and digital marketing are still dominant in academia, social media marketing is becoming more popular for both practitioners and researchers. The Modern Marketer does not miss any opportunity in utilizing the technological support available. Most social media platforms have built-in data analytics tools, which enable companies to track the progress, success, and engagement of ad campaigns. Companies address a range of stakeholders through social media marketing, including current and potential customers, current and potential employees, journalists, bloggers, and the general public. On a strategic level, social media marketing includes the management of a marketing campaign, governance, setting the scope (e.g. more active or passive use) and the establishment of a firm's desired social media "culture" and "tone."

So, in order to meet the demand of population, industries are increasing their production capacities and simultaneously some industries are polluting the environment by releasing waste in environment with out treating them and eventually affecting the ecosystem as these untreated waste pollutes not only water but also pollutes groundwater, land and air also and if it enter the plants through than it enter the food chain and ultimately affecting all the members of ecosystem. The soil samples were collected from different location and with the aim to improve manually contaminated soils samples by saline water, cow dung was used for treating those polluted samples. These soil samples were analyzed at laboratory to observe the role of Indian Cow dung in improving polluted soil. In soils samples collected from different location salty water was added and effects on electrical conductivity of that polluted s...

Heterostructures for In0.30Ga0.70As MOSHEMTs were grown using MOCVD on 200 mm Si substrates with record low threading dislocation density of < 2 × 107 cm−2. Devices with a Si-CMOS compatible front-end process were fabricated and the impact of the heterostructure design and doping on device performance is studied. Low subthreshold swing with minimum (Smin) down to 70 mV/decade was achieved by employing an InGaP top barrier layer and a cap doping of ∼2 × 1019 cm−3 was obtained with a Si-Te co-doping technique. An effective mobility (μ<inf>eff</inf>) of ∼4900 cm2/Vs at sheet electron density (N) of 3 × 1012 cm−2 was achieved which is record among InxGa<inf>1</inf>-xAs (x < 0.53) MOSFETs on Si substrates. In addition, current-gain cut-off frequency f<inf>T</inf>) of ∼60 GHz was extracted for 150 nm channel length MOSHEMTs.

Single carrier frequency division multiple access (SCFDMA) which utilizes single carrier modulati... more Single carrier frequency division multiple access (SCFDMA) which utilizes single carrier modulation at the transmitter and frequency domain equalization at the receiver is a technique that has similar performance and essentially the same overall structure as those of an OFDMA system. One prominent advantage over OFDMA is that the SC-FDMA signal has lower peak-to-average power ratio (PAPR). SC-FDMA has drawn great attention as an attractive alternative to OFDMA, especially in the uplink communications where lower PAPR greatly benefits the mobile terminal in terms of transmit power efficiency. SC-FDMA is currently a working assumption for the uplink multiple access scheme in 3GPP Long Term Evolution (LTE). In this paper, we give an in-depth overview of SC-FDMA with focus on physical layer and resource management aspects. We also show some research results on PAPR characteristics and channel-dependent resource scheduling of SCFDMA.

The major problem for the gear transmission is that the manufacturing of drugs is complex process which consumes longer and takes considerably precision and manufacturing cost is high .[1,2,4,7,8] The another major problem is that the transmission having gear cause the jamming thanks to the backless error and produces more noise compared to other drives thanks to pitch mismatch.[3] This elbow mechanism is additionally referred to as Gearless transmission , L-pin mechanism or Orbital mechanism . This elbow mechanism is straightforward in construction and may be easily made with minor precision. This mechanism is mainly utilized in replacement of bevel gears where the motion is to be transmitted at 900. So, generally elbow mechanism angle between rod is taken 900. [1,2,4,5,6,7,8,11,12,14] This mechanism also can be wont to transmit p...

Homogeneous charge compression ignition is a new combustion concept that gives benefits such as diesel like efficiency and resolves the problem of high level of NOx and PM simultaneously. It gives very high rate of heat release which cannot be easily controlled. The present work deals with development of HCCI engine and experimental investigations on petrol fuelled with DEE as ignition enhancer under two different compression ratios. Homogeneous mixture preparation is the most critical part of the HCCI combustion concept. To achieve homogeneous mixture of fuel and air, diethyl ether was used due to its low evaporating temperature around 35 o C. The mixture was inducted through a nozzle into the intake manifold specially fabricated for the engine under consideration. Constant speed experiments were performed to observe behaviour of HCCI combustion. The engine’s load carryin...

Scaffolding is a temporary or movable structure made of wooden planks and metal poles, used by workmen while building, repairing, or cleaning the building, bridges and all other man-made structures. It is also called ‘staging’ or ‘scaffold’. Scaffolds are widely used on construction site to get access to heights and areas that would be otherwise difficult to get to or to reach. Scaffolding, also called scaffold or staging, is a temporary structure used to support a work crew and materials to aid in the construction, maintenance and repair of buildings, bridges and all other man-made structures. Scaffolding is also used in adapted forms for formwork and shoring, grandstand seating, concert stages, access/viewing towers, exhibition stands, ski ramps, half-pipes, and art projects. Scaffold has to fulfill a diverse set of requirements: - creation of safe and productive working areas - providing ac...
