This project explores the development of a multiple input multiple output (MIMO) simulator using ray tracing techniques. This project gives an overview of ray tracing techniques, beamforming, MIMO channel models and MIMO systems. It explains the ability of MIMO systems to offer significant capacity increases over traditional wireless systems, by exploiting the phenomenon of multipath. By modelling high frequency radio waves as travelling along localized linear trajectory paths, they can be approximated as rays, just as in optics....
The design of b-glycosidases with planed substrate speciﬁcity for biotechnological application has received little attention. This is mostly a consequence of the lack of data on the molecular basis of the b-glycosidase speciﬁcity, namely data on the energy of the noncovalent interactions in the enzymetransition state complex.
The a-amylase family (glycoside hydrolase family 13;
GH 13) contains enzymes with approximately 30 specifi-cities. Six types of enzyme from the family can possess
a C-terminal starch-binding domain (SBD): a-amylase,
maltotetraohydrolase, maltopentaohydrolase, maltogenic
a-amylase, acarviose transferase, and cyclodextrin glu-canotransferase (CGTase). Such enzymes are multidomain
proteins and those that contain an SBD consist of four or
five domains, the former enzymes being mainly hydrolases
and the latter mainly transglycosidases. ...
Human glandular kallikrein 2 (hK2) is a trypsin-like serine protease expressed predominantly in the prostate epithelium. Recently, hK2 has proven to be a useful marker that can be used in combination with prostate speciﬁc antigen for screening and diagnosis of prostate cancer. The cleavage by hK2 of certain substrates in the proteolytic cascade suggest that the kallikrein may be involved in prostate cancer development; however, there has been very little other progress toward its biochemical characterization or elucidation of its true physiological role.
Tourism Marketing for Cities and Towns teaches readers how to develop a city’s brand to attract tourists and their spending. The brand that is developed will use a city’s already existing tourist attractions, distinctive cultural features, natural beauty, and/or heritage. These unique features plus the available tourist services can then be packaged together and promoted to tourist segments, including day visitors, business travelers, and traditional tourists.
Urban design is a diffuse and abstract term. It means different things to
different people. For those not directly involved in its practice or aware of
its effects on their daily lives, it may not mean much, if anything at all. I first
heard the term in architecture school, but I didn’t really think much about
what it might mean until my schoolmate Jonathan Barnett started using it
to describe his aspiration to put together with some of his colleagues a
design capability in the New York City government.
The book "Vietnam tourist guidebook" introduces the reader to the natural characteristics, social, traditional culture, art and tourist attractions of all the provinces and cities of Vietnam from north to south is about to sequenced alphabetically. Invite you to refer to the first book.

We normally think of the eye as an organ for vision, but due to the discovery of
additional nerve connections from recently-detected novel photoreceptor cells in
the eye to the brain, it is now understood how light also mediates and controls a
large number of biochemical processes in the human body. The most important
findings are related to the control of the biological clock and to the regulation of
some important hormones through regular light-dark rhythms. This in turn means
that lighting has a large influence on health, well-being and alertness.
The traditional direct marketing paradigm implicitly assumes that there is no possibility
of a customer purchasing the product unless he receives the direct promotion. In real
business environments, however, there are “voluntary buyers” who will make the
purchase even without marketing contact. While no direct promotion is needed for
voluntary buyers, the traditional response-driven paradigm tends to target such customers.
In this thesis, the traditional paradigm is examined in detail. We argue that it cannot
maximize the net profit.
In the Christian tradition, the doctrine of ‘just war’ has evolved throughout the last 1,700
years, originating with St. Augustine and later significantly shaped by St Thomas Aquinas,
both of whom developed ideas of the Greek philosopher Aristotle and the Roman philosopher
Saint Augustine (354-430) served as Bishop of Hippo for 34 years. His idea of just
war has two foundations. The first, owing much to the Eastern religious traditions, is that in
all things a person should not act out of selfish considerations.
Event tracing is a powerful and widely-used method for analyzing the performance of
parallel programs. In the context of developing parallel programs, tracing is especially
effective for observing the interactions between different processes or threads that occur
during communication or synchronization operations and to analyze the way concurrent
activities influence each other’s performance.
The problems of smog formation are exacerbated by a meteorological phenomenon
known as thermal inversion. Under normal atmospheric conditions, warm air in the vicinity
of a large city is trapped by an overlayer of cool air. Since warm gases tend to rise, they
normally diffuse upward and disperse the smog and other pollutants. A thermal inversion
occurs when the upper layer is a layer of warm air, while the polluted air near the ground is
relatively cool. In such a situation, the pollutant-laden cool air cannot rise and disperse.
Dehydrogenases and reductases are enzymes of fundamental metabolic
importance that often adopt a specific structure known as the Rossmann
fold. This fold, consisting of a six-strandedb-sheet surrounded bya-helices,
is responsible for coenzyme binding. We have developed a method to iden-tify Rossmann folds and predict their coenzyme specificity (NAD, NADP
or FAD) using only the amino acid sequence as input.
Many aspects of well-being of older persons are influenced by their living arrangements. In the Asian
context, and specifically in Cambodia, living with an adult child, especially a daughter, has been a
traditional pattern (Kato 2000). While household composition is the most common and readily available
indicator of living arrangements, it is important to recognize that the meaning and implications of
particular configurations defined by such information can be ambiguous.
The relative contributions to the specificity and catalysis of aglycone, of
residues E190, E194, K201 and M453 that form the aglycone-binding site
of ab-glycosidase from Spodoptera frugiperda(EC 184.108.40.206), were investi-gated through site-directed mutagenesis and enzyme kinetic experiments.
RNA-mediated gene silencing (RNA interference) is a powerful way to
knock down gene expression and has revolutionized the fields of cellular
and molecular biology. Indeed, the transfection of cultured cells with small
interfering RNAs (siRNAs) is currently considered to be the best and easi-est approach to loss-of-function experiments.
Dihydrofolate reductase (EC 220.127.116.11) is a key enzyme in the folate biosyn-thetic pathway. Information regarding key residues in the dihydrofolate-binding site ofMycobacterium aviumdihydrofolate reductase is lacking. On
the basis of previous information, Asp31 and Leu32 were selected as resi-dues that are potentially important in interactions with dihydrofolate and
antifolates (e.g. trimethoprim), respectively.
The substrate specificity of the xyloglucanase Cel74A fromHypocrea jeco-rina (Trichoderma reesei) was examined using several polysaccharides and
oligosaccharides. Our results revealed that xyloglucan chains are hydro-lyzed at substituted Glc residues, in contrast to the action of all known
xyloglucan endoglucanases (EC 18.104.22.168).
Somatic angiotensin-converting enzyme (ACE) contains two homologous
domains, each bearing a functional active site. Studies on the selectivity of
these ACE domains towards either substrates or inhibitors have mostly
relied on the use of mutants or isolated domains of ACE.
