Congestion occurs at the transport layer of the OSI model & is caused by buffer overflow because each node in WSN limited buffer space, energy and has limited resources. In WSN when the data travels from Source to Sink it has to pass through many intermediate nodes. Due to the event driven nature of WSN it leads to unpredictable network load as a result in congestion may occur at the nodes (i.e. intermediate nodes) which receive more data than the can forward and cause packet losses. The time during when intermediate nodes send WM to source to describe the congestion status will result in large amount of packet loss. This motivates the need of Load balancing at intermediate nodes. Our proposed work describes the multipath routing protocol which plays an important role in utilizing the available free spaces of the neighbored nodes and free routing paths to accommodate the load of Congestion Affected Node’s. In our work we also study the conges...

Such types of distributed cluster along with heterogeneous behavior will requires vast amount of scheduling efforts. Complexity increases as scheduler has to detect dynamic characteristics of the processors. Parallel schedulers are implemented in cluster technology for job assignment and placement. Further, core processor technology will provide a greater endeavor for load balancing. This research covers heterogeneous multiprocessors with 2-D mesh interconnection mapped to cube oriented memory mesh for job allocation and distribution. The job distribution will be based upon processor cycle speed. A two dimensional job slice is build, which in later stages along with many other slices overlapped to exhibit memory cube.

Initial policy structure includes no information about processor load but as the task groups arrive and get scheduled, this information acts as a prerequisite for next allocation. The task of load stability is tricky when static scheduling strategies are followed in allocation because these strategies require supplementary efforts to balance the load as the approaches designed so far do not follow load stability criteria during task allocation; rather they follow task adjustment to balance the load later on that enriches the overhead of context switching of tasks among processors. Context switching efforts not only includes the efforts for changing process address space, but position in ready queue is also affected. The work projected in this desertion performs load stability with priori information about processor utilization, based on this metric value processor space is partitioned among different categories. Depending on the load status, processors are categorized and an appropriate set out of those is identified that act as buddy for others and handles incoming queue. In other words stress free “buddy set” handles incoming job queue in place of their “stress underneath buddy set” processors so as to eliminate the pains of context switching and tasks adjustments after the tasks allocation.

The case of a 36-year-old woman with idiopathic resorption in the cervical areas of multiple teeth is presented. Her medical history was noncontributory, but her dental history was valuable in reaching a diagnosis. Hematologic and endocrinal investigations were unremarkable, but a computed tomography scan revealed relevant information. The progression of the lesion and involvement of multiple teeth without any pattern or chronology are challenges faced when diagnosing and treating this condition.

The substrates were fabricated simply using a low vacuum air plasma scanning electron microscope gold coater and annealing using a hot plate. The measured permittivity profile and optical transmission characteristics of such substrates showed large changes before and after annealing, with clear changes in the occurrence and position of the LSPR in the visible spectrum. Furthermore, the LSPR wavelength of these substrates was tuned from 537 nm to 630 nm using cyclic deposition and annealing. It was observed that every anneal step could be used to blue shift the resonance, while a deposition step could be used to red shift the resonance, thus giving rise to a wide tunability. We also present the k-space images of the substrates using narrowband fluorescence leakage radiation microscopy and broadband polarization microscopy. The enhanced scattering in these substrates was clearly imaged in the k-space, and the color content in the broadband k-space images correlates well with the spectral characteristics of these substrates that can be used in commercial quality testing without a spectrometer. The optical characteristics of the substrates were attributed to the morphology evolution verified using scanning probe microscopy. A single particle model based simulation was used to evaluate the optical response. The substrates were then tested for surface enhanced Raman spectroscopy (SERS) activity using control experiments involving Rhodamine 6G dye in PMMA matrix of different concentrations with analyte volumes of approximately 200 pl and analytical enhancements of >3×10^4 (net enhancement >1.8×10^7 ) were obtained. The limit of detection was ≈ 10 nM in low volume (≈200 pl) analyte, reaching the regime of few molecule detection. To establish the relevance of the substrates for bio-sensing, surface functionalization using thioglycolic acid was measured using SERS.

Parallel hardware design can employ array processors, pipelined system which can be further extended to scalar and super scalar pipelined systems. Other hardware designs proposed, is based upon multiprocessors or they may be designed as distributed parallel cluster systems. In this paper, multi-computers are the basic hardware for cluster design over the local area network covering analysis of matrix multiplication with strassen's algorithm. The estimated results are then compared with traditional matrix multiplication algorithm. Strassen's multiplication approach reduces one multiplication out of eight by computing arithmetic additions/subtractions for each 2×2 matrix. High performance can be achieved as the idea is extended over to multi-computer cluster for large sized matrices. This work covers analysis of Strassen's ability of divide and conquers to run in parallel by decomposing matrix size over cluster machines covering data parallel aspects with SIMD based computational model , where each cluster machine performs its own recursive divide and conquer approach as defined by strassen's methodology [10] to obtain partitioned matrix multiplication. Finally, the detailed distributed experiment along with connectivity interface and implementation will be discussed.

The sample of the survey consisted of Indian OMFS post-graduate residents attending the "1st Asian Oral and Maxillofacial Surgery PG Convention" held from 29th to 31st August, 2013 at Mangalore, India. Questions were asked regarding the participant's preferred tooth replacement modality, the transplantation procedure (socket preparation and stabilization of transplanted tooth); fate of the transplanted tooth (pulpal and periodontal fate) and the possibility of replacing second molars with such procedure, cross-arch transplantation and transplantation after new-socket preparation. The responses of 1st, 2nd and 3rd year residents were assessed for statistical significant difference using Fishers exact test. Out of 434 residents surveyed using a pre-tested self-administered questionnaire, 287 residents responded (response rate 66 %). 74 % were aware of the possibility of autogenous third molar transplantation. Only 24 % believed a new periodontal ligament would form around the transplanted tooth. Misconceptions regarding pulp healing, socket preparation and tooth stabilization and new alveolus transplantation were also seen. 44 % had never seen the procedure and 74 % had never performed it themselves. No statistical significant difference was seen among the responses classified according to the year of training. OMFS residents were found to have inadequate knowledge regarding autogenous tooth transplantation. Tooth transplantation needs to be included in the dental curriculum and standard OMFS textbooks with practical training in post-graduation period.

Various terms, such as enamel renal syndrome, amelogenesis imperfecta and gingival fibromatosis syndrome, and enamel-renal-gingival syndrome, have been used for patients presenting with the dental phenotype characteristic of this condition, nephrocalcinosis or nephrolithiasis, and gingival findings. This report describes a case of amelogenesis imperfecta of the enamel agenesis variety with nephrolithiasis in a 21-year-old male patient who complained of small teeth. The imaging modalities employed were conventional radiography, cone-beam computed tomography, and renal sonography. Such cases are first encountered by dentists, as other organ or metabolic diseases are generally hidden. Hence, cases of amelogenesis imperfecta should be subjected to advanced diagnostic modalities, incorporating both dental and medical criteria, in order to facilitate comprehensive long-term management.

This resonance has been conventionally attributed to dipole oscillations in the arms parallel to the incident E-¯eld (vertical arm), while neglecting the e®ect of arm perpendicular to the incident E-¯eld (horizontal arm) that has been described in the past as the cut-wire approximation. In order to study the e®ect of horizontal arm on electrical resonance, several geometrical modi¯cations of SqSRR consisting of identical vertical arms with varying horizontal arm lengths, were designed, fabricated and characterized at frequencies from 0.1 to 0.3 THz, at normal incidence. Contrary to the cut wire approximation, signi¯cant shift in electrical resonance frequency was observed with varying horizontal arm lengths of SqSRR. The presented experimental results and analysis based on the surface current pro¯le in these structures, indicate the necessity to include the e®ect of horizontal arm in design of SqSRR. The shifts in plasma frequency with variation in horizontal arm length is explained as dilution of the e®ective electron density of the vertical arm. Simple modi¯cation in existing models for plasma frequency and electrical resonance frequency is proposed to consider the e®ect of horizontal arm lengths. Experimental and simulated results were found to be in good agreement with the proposed model.

It introduces techniques for modifying and using powered wheelchairs as mobile platforms enabling communication and remote control. The wheelchair is equipped with a laptop computer, a CCD camera and a wireless network interface card (NIC) for 802.11b Internet access. The laptop acts as a server allowing network clients to gain access through a custom control interface on the chair. The remote controlling client receives a video and audio feed from the chair and sends control signals for maneuvering. While traveling, the chair is able to change its network association from one access point (AP) to another within the same subnet-the process is known as handoff. However, there is no inter-network handoff mechanism presently available in IP networks. This restricts the mobility of the wheelchair to within the coverage area of the subnet APs. This paper shows that the Internet engineering task force's (IETF) network layer mobility protocol-Mobile IP suffers from large handoff latencies that can hinder communication between the client and the wheelchair during handoff. Mobile IP alone is not a sufficient solution for a mobile telebotic system such as NEPWAK. An interesting solution to the handoff latency problem comes from the Fast-handover protocol described in Section 4.4 with simulation results in Section 6.2.

This must be achieved by workload partitioning & characterization, directs towards the development of Multiprocessor machines, a way to achieve parallel effects. Today, multiprocessor systems cover H/W replications that may replicates complete central processing units asynchronously or multiple executional units synchronously controlled by a different/common clock respectively. This research deals with the multiprocessor scheduling implemented via simulated time sharing environment containing logically programmed virtual processors and batch lists, each batch having its associated arrival time along with number of jobs where each job contains parameters such as Batch_id, Job_id and CPU Burst_time(defined as no. of cycles required) etc. The idea behind this theory is to distribute a number of simultaneously occurring jobs to virtual processor list corresponding to a scheduling algorithm. Synchronous architectures involve SIMD based model with data parallel aspects of computations, whereas Control parallel asynchronous MIMD machines are the future trends leading towards Instruction level parallel processors involving VLIW (very large instruction word) and superscalar machines.

A patient with continuing pain in mandibular left first molar even after completion of biomechanical preparation was referred by a dentist. Following basic laws of the pulp chamber floor anatomy, 8 canals were located in three steps with 4 canals in each root. In both of the roots, 4 separate canals commenced which joined into two canals and exited as two separate foramina. At 6 mon follow-up visit, the tooth was found to be asymptomatic and revealed normal radiographic periapical area. The case stresses on the fact that understanding the laws of pulp chamber anatomy and complying with them while attempting to locate additional canals can prevent missing canals.

This must be achieved by workload partitioning & characterization, directs towards the development of Multiprocessor machines, a way to achieve parallel effects. Today, multiprocessor systems cover H/W replications that may replicates complete central processing units asynchronously or multiple executional units synchronously controlled by a different/common clock respectively. This research deals with the multiprocessor scheduling implemented via simulated time sharing environment containing logically programmed virtual processors and batch lists, each batch having its associated arrival time along with number of jobs where each job contains parameters such as Batch_id, Job_id and CPU Burst_time(defined as no. of cycles required) etc. The idea behind this theory is to distribute a number of simultaneously occurring jobs to virtual processor list corresponding to a scheduling algorithm. Synchronous architectures involve SIMD based model with data parallel aspects of computations, whereas Control parallel asynchronous MIMD machines are the future trends leading towards Instruction level parallel processors involving VLIW (very large instruction word) and superscalar machines.

A patient with continuing pain in mandibular left first molar even after completion of biomechanical preparation was referred by a dentist. Following basic laws of the pulp chamber floor anatomy, 8 canals were located in three steps with 4 canals in each root. In both of the roots, 4 separate canals commenced which joined into two canals and exited as two separate foramina. At 6 mon follow-up visit, the tooth was found to be asymptomatic and revealed normal radiographic periapical area. The case stresses on the fact that understanding the laws of pulp chamber anatomy and complying with them while attempting to locate additional canals can prevent missing canals.
