ABSTRACT Advancement of technologies has resulted in the innovation of new engineering materials which are very difficult to machine with conventional machining process. Non-conductive ceramic materials are one of them. These have become important for various industrial applications .Their applications are increasing rapidly in industrial and engineering applications due to its high hardness, low thermal […]

ABSTRACT Construction site planning affects the construction progress, safety, and functioning of various resources especially in hilly regions where space is always limited. In hilly regions, proper allocation of space for various resources keeping in view the site safety is difficult due to the involvement of number of resources and interlinked constraints. This affects site […]

ABSTRACT Mechanical properties of epoxy composite reinforced with recycled plants fibers were studied. Impact strength, tensile strength, flexural strength and hardness were studied for composite material. These fibers were mixed with polypropylene resin in different reinforcement percentage (0%-60%) and the effect on the above mechanical properties was studied. It has shown an enhancement in these […]

ABSTRACT With the huge growth of computer networks and the latest advances in digital technologies, a huge amount of digital data is being exchanged over various types of networks. It is true that a large part of the information is either confidential or private. As a result, different techniques have been used to provide the […]

ABSTRACT This paper presents a design of planar microstrip patch antenna (MPA) with full ground plane which is able to operate at 5.5 GHz frequency with 200MHz band. The return loss at 5.5 GHz is -29.5dB for inset feed antenna. Maximum gain of this antenna is 5.7dB. Return loss is improved after introducing a pyramidal […]

ABSTRACT Bismuth layer-structured ferroelectric (BLSF) compound barium bismuth niobate (BBN) with a chemical formula BaBi2Nb2O9 has been prepared using a solid-state reaction technique. Preliminary structural and microstructural properties of the compound were investigated through X-ray diffraction technique and SEM-microphotographs respectively. Its dielectric properties have been analyzed within a wide range of temperature and frequency. Relative […]

ABSTRACT Different location update algorithms have been analyzed. Both Static location and movement based location schemes been analyzed with different cell sectors. Dynamic LM schemes have higher signaling traffic as compared to static LM schemes. The location updates are also measured over different cell structures. The reuse factors of cells are measured for different cell […]

ABSTRACT Isolated operation and control of induction motor fed from a solar photovoltaic array along with resistive loads is presented in this paper.  New controllers are proposed to control the induction motor used for water pumping systems and for controlling of resistive loads with the varying solar irradiation are proposed. The simulations are performed in […]

ABSTRACT A number of biometric techniques have been used for personal identification such as face recognition, fingerprint recognition, voice recognition and signature recognition. However signature verification is most widely used. Signature being the most prominent handwritten proof of identity is used for authentication of documents in the fields of financial, commercial and legal transactions which […]

ABSTRACT The aim of present paper was to study the biodegradation of 2,4,6- trinitrotoluene (TNT) in waste water using free cultures of a bacterial strain Acinetobacter noscomialis isolated from a TNT contaminated site. Three operating variables i.e. pH, initial TNT concentration and time for degradation were studied using response surface methodology (RSM), involving Box-Behnken design. […]
