Lattice Dynamics 2.1 Introduction The discussion has been done in chapter1 about the nature crystal structure of Silicon Carbide and its properties was under the equilibrium condition, which means the location of each atom is restricted at its lattice site. The vibration of atoms about their equilibrium sites will be considered in this chapter. The fundamental reason of this vibration is thermal and the lowest achievable energy (i.e. zero-point energy). The forces acting on atoms tend to always…

Flash Technologies’ strategy and its key business objectives Flash Technologies is a rapidly growing high-tech company primarily in the flash memory cards industry. It manufactures flash memory cards, USB flash drives, and solid-state hard drives for computers and other electronic devices. It sells its flash memory primarily to original equipment manufacturers (OEMs). The company’s strategy is to 1. Provide a full range of services, including designing, programming, and manufacturing of flash…

Rochelle salt among them) which were subjected to mechanical anxiety. These outcomes were a sound representative for the Curies ' creative ability and persistence, considering that they were gotten with simply tinfoil, paste, wire, magnets and a crystal specialist 's saw. In the investigative circles of the day, this impact was considered a significant "revelation," and was immediately named as "piezoelectricity"…

enantiomers are always exactly opposite. Theory. For each electronic transition one can define an electric (µij≠0) and a magnetic (mij≠0) transition dipole. Both can lead to absorption of radiation, the intensity of which is directly related to the oscillator strength f, fij≈| µij |2+ | mij |2 In CD spectroscopy, in contrast to an electronic absorption (where electronic dipole >> magnetic dipole) spectroscopy, both transition dipole moments are important. Therefore, an integral of CD (Rij)…

Surveillance is defined as it is the monitoring of activities, behavior or changing information usually of people for the purpose of influencing ,directing or protecting purpose. The word surveillance is French word “ watching over”, ‘sur’ means “from above ” and ‘veiller’ means “to watch”. Surveillance is also observation from a distance by means of electronic equipment. Surveillance is one of the most important security system in today’s life as it protects home from theft , burglaries and…

CAREER EPISODE-I INTRODUCTION 1.1 I had completed the project with topic “Robert control via wireless transmission” as a compulsory requirement to meet the criteria for degree of bachelor of electronics and communication engineering purposed by department of electronics and computer department of IOE, western regional campus, Lamachoor, pokhara. Mainly, project presents both hardware and software implementation for developing radio frequency based control mechanism via wireless…

Chapter 3 Experimental Setup 3.1 Test rig components and description: Fig. 3 illustrates schematic view of the test rig of an IDX-SAHP system. It was designed for a typical UK home administering up to 350 L/day of DHW. The main components are numbered in (Fig.3). The evacuated tube collector installed outdoor on a south facing roof has a surface area of 3.021 m2 with a 52-degree inclination (tilt angle). A 300L, stainless steel, insulated water storage tank has two coils immersed inside, one for…
