Predicting vehicular travel times by modeling heterogeneous influences between arterial roads

Predicting travel times of vehicles in urban settings is a useful and tangible quantity of interest in the context of intelligent transportation systems. We address the problem of travel time prediction in arterial roads using data sampled from probe vehicles. There is only a limited literature on methods using data input from probe vehicles. The spatio-temporal dependencies captured by existing data driven approaches are either too detailed or very simplistic. We strike a balance of the existing data driven approaches to account for varying degrees of influence a given road may experience from its neighbors, while controlling the number of parameters to be learnt. Specifically, we use a NoisyOR conditional probability distribution (CPD) in conjunction with a dynamic bayesian network (DBN) to model state transitions of various roads. We propose an efficient algorithm to learn model parameters. We propose an algorithm for predicting travel times on trips of arbitrary durations. Using synthetic and real world data traces we demonstrate the superior performance of the proposed method under different traffic conditions.Comment: 13 pages, conferenc

Numerical Simulation of Compression Ignition Diesel Injection (CIDI) to investigate Performance parameters

This paper describes the requirement of the Numerical simulation of compression ignition diesel injection by the use of computer language and it also compares the performance parameter for the biodiesel such as jatropha and karanja. The Engine test was carried out in 512 Army base workshops for the experimental validations. It was carried out on SAJ dynamometer which was installed in Engine test house for testing of Engines. Performance parameters such as Brake power, Brake Torque, Mechanical efficiency, Thermal Efficiency, Pressure vs Crank angle and Heat release Rate vs Crank Angle was taken from the Engine test house. The Program code for the Performance parameter of Engine was developed in C++ language. Then the simulation was carried out. The simulation results were compared and analyzed with the experimental results. The final results was effective for compression ignition diesel injection. As we know that today’s world is approaching towards computer simulated results, so the numerically simulated results will save time and money for engine testing house. Likewise we can approach towards numerical simulation for various types of Engines

Anatomical Perspective of Ancient Ayurveda: A Comparative Review Amongst Ayurveda Samhita’s

Anatomy is one of the oldest modality of medical system and enough facts are available in ancient India regarding the practice and knowledge of anatomical science. It is believed that the ancient Indian scientist explored important and essential knowledge of practical anatomy. The concept of surface anatomy came in practice from the knowledge of cave paintings of animals presented with critical area of animal body. The Rigveda is one of the Vedas along with three others; Yajur, Sama and Atharva encompass knowledge about lungs, heart, stomach and kidneys. The Atharva Veda described about medicinal herbs and plants, Atharva Veda also refers about Dhamanis as ducts equivalent to arteries and Siras as ducts equivalent to veins. Similarly other ayurveda or ancient texts provides great knowledge about the human anatomy and physiology. Present article summarizes ayurveda perspective on traditional Indian knowledge about the human body. Keywords: Ayurveda, Samhita, Anatomy and Physiology

Design of high performance class B push pull amplifier

Class B push pull amplifier are the most commonly used circuit for amplification purpose due to its higher efficiency. In spite of having a very high efficiency, crossover distortion is one which severely affects the performance of Class B amplifier. It can be reduced by the use of op-amp as a negative feedback op-amp. The op-amp can also be used a buffer. The use of diode creates a dead band in the output voltage. The heating effect in the diode is reduced by the use of temperature compensation feedback resistor

Classical presentation of Shaarira Rachana w.s.r. to Vedas, Samhitas and other ancient literatures

Ayurveda is considered as traditional Indian medical system which encompasses great knowledge about human anatomy and physiology. Acharya Susruta presented several aspects related to human anatomy along with utility of dissection process. The ancient Acharya of Indian system emphasizes structural organization of human body. Susruta has described anatomical aspects of body in Sharira sthana; this section emphasizes that origin of universe can be correlated with physical and metaphysical state of body. The ancient Acharya presented human body as an extension of the embryo. The classical texts presented several concepts related to the human anatomy (Rachana Shaarira) and this article elaborated same

Spin dynamics in the diluted ferromagnetic Kondo lattice model

The interplay of disorder and competing interactions is investigated in the carrier-induced ferromagnetic state of the Kondo lattice model within a numerical finite-size study in which disorder is treated exactly. Competition between impurity spin couplings, stability of the ferromagnetic state, and magnetic transition temperature are quantitatively investigated in terms of magnon properties for different models including dilution, disorder, and weakly-coupled spins. A strong optimization is obtained for T_c at hole doping p << x, highlighting the importance of compensation in diluted magnetic semiconductors. The estimated T_c is in good agreement with experimental results for Ga_{1-x}Mn_x As for corresponding impurity concentration, hole bandwidth, and compensation. Finite-temperature spin dynamics is quantitatively studied within a locally self-consistent magnon renormalization scheme, which yields a substantial enhancement in T_c due to spin clustering, and highlights the nearly-paramagnetic spin dynamics of weakly-coupled spins. The large enhancement in density of low-energy magnetic excitations due to disorder and competing interactions results in a strong thermal decay of magnetization, which fits well with the Bloch form M_0(1-BT^{3/2}) at low temperature, with B of same order of magnitude as obtained in recent squid magnetization measurements on Ga_{1-x}Mn_x As samples.Comment: 13 pages, 14 figure

Live tracking of saline for betterment of patient

In hospitals, Saline is fed to patients to treat dehydration and use of saline improves their health. In current health care measures, whenever a saline is fed to any patient, the patient must be continuously monitored by nurse, doctor or caretaker. So basically, in all the hospitals nurse or caretaker is responsible for monitoring of saline. Due to the avoidance of nurses towards the saline level monitoring or lack of knowledge it can harm to the patients health. Therefore, to stop the patient from obtaining injured and shield their lives throughout saline feeding amount, the saline level observance system are developed. The planned system is made Internet web of Things (IoT) platform. The planned system includes of devices which can act as tier sensor for observance the crucial level of the saline within the saline bottle. Whenever the amount of the saline reaches to the predefined crucial level, then the nurses, caretaker, doctors are alerted through the alarm associate in Nursing an alert message are sent through the utilization of web to the involved nurses and doctors that there's a requirement for replacement of the saline bottle. This planned system may be utilized efficiently in homes as well as hospitals

Twak Sharir According to Ayurveda and its Correlation with Skin Diseases: Ayurveda and Modern Consideration

Twak (skin) is one of the important sensory organs (Dnyanendria) which receive sense/stimuli through Adhisthanas. Twak generates anticipated response against the stimuli like; Sparsh (touch). Twacha (skin) not only helps to understand touch sensation but it also covers whole body, protect from shock and perform functioning of thermostat through sweat channels (swedvahi strotas). The pores present in skin help in the hair nourishment and detoxification process. It is believed that each and every components of skin having anatomical as well as physiological importance. Therefore any anatomical or physiological abnormalities in skin or related organs may leads various disorders with skin manifestation including psoriasis, acne, leprosy, hyper pigmentation, skin allergy and vitiligo. Present article described structural components of skin and their role in disease pathogenesis. Keywords: Ayurveda, Dnyanendria, Twak, Skin, Disorders. &nbsp;&nbsp;&nbsp;&nbsp;&nbsp
