Import 05/08/2014Zadáním této bakalářské práce je návrh a realizace optoelektronické reflexní závory, která pomocí zaznamenaných výsledků dokáže vyhodnotit a rozpoznávat směr pohybu procházející osoby dveřním rámem. Teoretická část této práce obsahuje především informace o optickém záření, důležité parametry optických závor a detailnější rozbor optických vysílačů a detektorů. Praktická část už je soustředěna na samotný návrh a realizaci optoelektronické závory. Elektrická schémata a schémata plošných spojů vysílacích a detekčních částí závory byly navrženy pomocí programu Eagle. Pro vyhodnocení signálů byl použit mikrokontrolér firmy Atmel typu ATMEGA2560, který je hlavní řídící jednotkou platformy Arduino Mega 2560. Mikroprocesor Arduina byl naprogramovaný pomocí jeho originálního jazyku Wiring k vyhodnocení směru pohybu a zápisu tohoto výsledku na zobrazovací jednotku počítače pomocí sériového přenosu. Jako zobrazovací prostředí je použita aplikace pro obsluhu sériového portu terminál Hercules Setup.This bachelor thesis deals with design and execution of reflective optoelectronic doorframe bar, which is able to detect and analyse passing object’s direction of movement through the doorframe. Main objective of theoretical part is to acquaint with information about optical radiation, essential features of optical bars and in-depth analysis of optical transmitters and detectors. Practical part is therefore focussed on the design and the execution itself. Electric schemes and printed circuit board schemes of emitting and detection bar parts have been designed using Eagle software. Atmel’s ATMEGA2560 microcontroller was used as the primary signal analysis control unit of the Arduino Mega 2560 platform. Arduino microprocessor was designed using it’s original Wiring processing language for movement direction analysis and subsequently for reflecting the results on computer display unit using serial communication. For operating with serial port was chosen terminal Hercules Setup software.450 - Katedra kybernetiky a biomedicínského inženýrstvívýborn

PENGARUH PEMBERIAN AMPAS KEDELAI DAN BUNGKIL INTI SAWIT YANG DIFERMENTASI DENGAN ASPERGILLUS NIGER TERHADAP BAKTERI USUS BROILER

Salah satu cara yang telah dilakukan untuk meningkatkan produktivitas broiler, antara lain dengan memberikan Antibiotic Growth Promotor (AGP). Pemberian AGP dalam ransum bertujuan merangsang pertumbuhan, memperbaiki efesiensi pakan, dan menekan angka kematian. Namun pemberian AGP dalam pakan sudah dilarang karena dapat menimbulkan berbagai masalah bagi kesehatan ayam dan juga kesehatan konsumen. Salah satu upaya dilakukan dengan mengembangkan alternatif lain melalui pakan yang mengandung growth promotor alami berupa probiotik seperti A. niger yang dibiakkan pada ampas kedelai dan bungkil inti sawit (AKBIS). Pemberian AKBIS fermentasi ini juga dapat memperbaiki kualitas bahan pakan.Tujuan penelitian ini adalah untuk mengetahui pengaruh pemberian AKBIS yang difermentasi dengan A. niger terhadap mikroflora saluran pencernaan broiler. Sampel saluran pencernaan ayam diperoleh dari 80 ekor broiler yang dibagi menjadi empat perlakuan, setiap unit empat ekor. Setiap perlakuan terdiri dari 5 ulangan yang diberi pakan perlakuan selama 21 dan 35 hari dengan penambahan empat konsentrasi pakan fermentasi yang berbeda (0%, 2%, 4%, 6% dari total pakan). Saluran pencernaan broiler diperiksa ALT mikroba, E.coli, Salmonella dan BAL. Data dianalisis dengan uji Anava melalui program SPSS for windows versi 17,0 dan dilanjutkan dengan uji Duncan.Hasil penelitian menunjukkan bahwa AKBIS yang difermentasi dengan A. niger berpengaruh nyata (

Using 'The Apprentice' to Teach a Managerial Economics Course

This paper describes a game based on a television show known as "The Apprentice" that can be used in a managerial economics course. After assigning students to teams and giving them tasks to complete, students are able to experience first-hand what it is like to make real-world business decisions and to face the consequences of their actions. In addition, students have the opportunity to apply what they learn in the game to many course related topics. The main goal of this activity is to create an active learning environment that is conducive to helping students develop analytical skills.

Incorporation of Interprofessional Education and Special Care Dentistry into Standard Dental School Curriculum

According to dentistry, special needs is defined as individuals whose medical, physical, psychological, or social situations may make it necessary to modify normal dental routines in order to provide dental treatment for that individual. The population of special needs patients is increasing. The lack of educated professionals in special care dentistry is leading to severe and untreated systemic and oral health problems in the special needs population. The implementation of interprofessional treatment for special needs individuals has proven to be the most effective method of treatment within the special needs population. This study examines the current application of special care dentistry and interprofessional education curriculum through the analysis of case studies and surveys in order to establish a reform that provides a more comprehensive implementation of classes that train oral health professionals on how to treat special needs patients. Despite newly established accreditation standards, graduating dental students are adequately prepared to engage in the treatment of special needs patients. Some studies have suggested that a mandatory post graduate year for dental students will correct this problem, however, this is an expensive solution that would present a financial burden to dental students. A system that combines special care and interprofessional education courses into a didactic and hands-on learning curriculum that will fit into curricula and surpass the CODA accreditation standards. Forming a universal special care dentistry curriculum taught through an interprofessional approach, special needs patients will not only receive better care but cost and treatment will improve as well.https://scholarscompass.vcu.edu/uresposters/1200/thumbnail.jp

Crystal plasticity and phenomenological approaches for the simulation of deformation behavior in thin copper alloy sheets

In the expanding context of device miniaturization, forming processes of ultra thin sheet metals are gaining importance. Numerical simulation of these processes requires accurate material modeling. In this study, both the phenomenological modeling approach and the crystal plasticity finite element method (CPFEM) are considered. Theoretical definitions of both models, numerical implementation as well as their parameter identification procedures are outlined. Subsequently they are compared on a one to one basis, mainly with regards to their ability to predict mechanical responses for a variety of strain loading paths.Agence Nationale de la Recherche, ANR-12-RMNP-0009-0

The Association of Advanced Math Course-Taking by American Youth on Subsequent Receipt of Public Assistance

Helping people move to independence is often cited as a primary goal of public assistance policies in the United States. Over the past several decades, welfare reform efforts in the US have promoted the idea of a work-first approach. Research shows that this approach has discouraged or at least made it harder for some students to attend college while meeting the work requirements for aid. How can those students who need public assistance increase their chances of finding a sustainable job and thus not need to rely on the public support system after high school? To address this question, this study used a sample of 3,384 student responses from the National Longitudinal Study of Adolescent to Adult Health and a recursive bivariate probit model to analyze the association between advanced math course-taking in high school and the probability of subsequent receipt of public assistance. The empirical results suggest that taking advanced math courses in high school is associated with a lower probability of receiving public assistance for recent graduates. These findings are particularly important for school social workers who work in conjunction with teachers and school counselors to help at-risk students improve their chances of future financial independence
