CHAPTER-1 INTRODUCTION OVERVIEW Multimodal biometric face and fingerprint recognition using XOR configuration system based on adaptive principal component analysis and multilayer perception. Multimodal biometric is a combination of physiological and behavioral characteristics into a single biometric system. The important cause to combine singular traits is to get improve recognition rate and accurate result. This is done when feature and trait of biometric are statistically independent. The…

There are many convieneces to solar power, but of course nothing is perfect. It is more convienet for the consumer because they will not have to purchase things to run their house or car, they could just have the solar pannels themselves and be independent. The one and major inconveience of solar power is what do you do on a cloudy day? Or if one place does not get a lot of sun how can it run? Advantages: Solar energy is a renewable resource that is environmentally friendly. Unlike fossil…

representation for better understanding the mechanism of thermoelectric effect is shown in Figure 5.1. Here, the diffusion of charge carriers between the hot and cold junctions in a pair of semiconducting materials when there is a temperature difference applied between them is demonstrated. Usual thermoelectric system has a pair of n- and p-type semiconductor materials (thermocouple) for obtaining a large thermoelectromotive force. This effect can also be used to determine the temperature or…

SMILE CORRECTION BY GINGIVAL DEPIGMENTATION AND LIP REPOSITIONING A CASE REPORT ABSTRACT Excessive gingival display during smiling (“gummy smile”) with hyperpigmented gums is an esthetic concern for the patients. Gummy smile can be managed by different treatment modalities based on specific diagnosis. This case report demonstrates the management of a 22 years old female patient with the chief complaint of dark gums and excessive gingival display while smiling due to hypertonic lip. Treatment…

When Tone Has a Different Meaning The communication I’ve chosen is my one of the experiences I have had with my wife. She and I were discussing the way we communicate with our child. She brought up the fact that we should really take the time to pay attention to our tone when discussing certain topics that our child might receive in a negative manor. Of course, when one dives into the meaning of the word tone, it is important to look at the definition as it pertains to the topic. It states “a…

o. Primary active transport 14. If the solute concentration is greater in the solution on the inside of the cell, compared to the solute concentration of the solution that is outside the cell, then what direction will water move? p. into the cell 15. In this transport process, the energy stored in Na+ or H+ concentration gradient is used to drive other substances across the membrane against their own concentration gradients. q. Secondary active transport 16.…

There are different mythology related to Mount Fuji according to Buddhist and Shinto traditions. According to Buddhist mythology, Mount Fuji was named after the fire goddess Fuchi who represents inspiration, courage, safety (protection), fire (ancient), skill (sports), and relationships. As a fire goddess, she rules natural energy sources and those generated within ourselves. This energy, along with summer’s sun, joins together in our life today, generating strength, endurance, keen vision and…

in PD and control groups, 29,83±2,13kg/m2 and 31,96±1,66kg/m2,(p=0,000), and 25,43±2,16kg/m2 and 26,82±1,69kg/m2(p=0,002), respectively. There were statistically significant difference between weight, fat mass, bone mass, BMR and BMI in men in PD and control groups, 76,47±11,71 and 82,64±11,08 (p=0,005); 18,32±6,13 and 21,55±7,84 (p=0,01); 2,91±0,37 and 3,04±0,27 (p=0,03); 1679±236 and 1775±179 (p=0,01); 27,40±3,58 and 28,88±3,52 (p=0,02), respectively. In women there were statistically…

and capacitance value of 2mF. Fig. 6.4 Boost Converter 6.3 MPPT ALGORITHM (P&O): This is the most commonly used algorithm for maximum power point tracking. In this algorithm the controller adjusts the voltage by using the array voltages. If the power increases, it adjusts until the power stops increasing and sets the value. It is also called as hill climbing method. Fig. 6.5 P&O Algorithm Fig. 6.6 Simulink model for P&O Algorithm 6.4 VOLTAGE CONTROL LOOP: The main purpose of this…
