Advanced Roaming in Wi-Fi Networks

Tato práce se zabývá problematikou Wi-Fi roamingu. Popisuje a přibližuje jak k této problematice přistupují doplňky standardu 802.11 zaměřující se na podporu roamingu, tedy doplňky 802.11r, 802.11k a 802.11v. Součástí této práce je sestavení topologie založené na sytému OpenWrt, na které je testován roaming před a po nasazení těchto standardů. Po testování je ukázán kratší čas roamingu, kterého je dosaženo díky použití těchto standardů. Rovněž je zde sestavena identická testovací topologie založená na zařízeních Mikrotik, na které je otestováno, že zařízení Mikrotik tyto standardy nepodporují.This work deals with the issues of Wi-Fi roaming. It describes, how amendments of IEEE 802.11 focused on roaming, namely 802.11r, 802.11k and 802.11v, deal with these issues. Part of this work is designing a topolgy based on OpenWrt system, on which to test roaming before and after using these amendments. After testing, lower roaming times are exhibited, thanks to using these standards. There is also designed an identical topolgy based on Mikrotik devices, on which it’s demonstrated, that Mikrotik devices do not support these standards.

Mu, delta, and kappa opioid receptor mRNA expression in the rat CNS: An in situ hybridization study

The Μ, Δ, and Κ opioid receptors are the three main types of opioid receptors round in the central nervous system (CNS) and periphery. These receptors and the peptides with which they interact are important in a number of physiological functions, including analgesia, respiration, and hormonal regulation. This study examines the expression of Μ, Δ, and Κ receptor mRNAs in the rat brain and spinal cord using in situ hybridization techniques. Tissue sections were hybridized with 35 S-labeled cRNA probes to the rat Μ (744–1, 064 b), Δ (304–1,287 b), and Κ (1,351–2,124 b) receptors. Each mRNA demonstrates a distinct anatomical distribution that corresponds well to known receptor binding distributions. Cells expressing Μ receptor mRNA are localized in such regions as the olfactory bulb, caudate-putamen, nucleus accumbens, lateral and medial septum, diagonal band of Broca, bed nucleus of the stria terminalis, most thalamic nuclei, hippocampus, amygdala, medial preoptic area, superior and inferior colliculi, central gray, dorsal and median raphe, raphe magnus, locus coeruleus, parabrachial nucleus, pontine and medullary reticular nuclei, nucleus ambiguus, nucleus of the solitary tract, nucleus gracilis and cuneatus, dorsal motor nucleus of vagus, spinal cord, and dorsal root ganglia. Cellular localization of Δ receptor mRNA varied from Μ or Κ, with expression in such regions as the olfactory bulb, allo- and neocortex, caudate-putamen, nucleus accumbens, olfactory tubercle, ventromedial hypothalamus, hippocampus, amygdala, red nucleus, pontine nuclei, reticulotegmental nucleus, motor and spinal trigeminal, linear nucleus of the medulla, lateral reticular nucleus, spinal cord, and dorsal root ganglia. Cells expressing, Κ receptor mRNA demonstrate a third pattern of expression, with cells localized in regions such as the claustrum, endopiriform nucleus, nucleus accumbens, olfactory tubercle, medial preoptic area, bed nucleus of the stria terminalis, amygdala, most hypothalamic nuclei, median eminence, infundibulum, substantia nigra, ventral tegmental area, raphe nuclei, paratrigeminal and spinal trigeminal, nucleus of the solitary tract, spinal cord, and dorsal root ganglia. These findings are discussed in relation to the physiologica functions associated with the opioid receptors.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/50064/1/903500307_ftp.pd

Biochemistry and physiology of gastrointestinal somatostatin

Somatostatin, a tetradecapeptide initially isolated from the ovine hypothalamus, is widely distributed throughout the gastrointestinal tract where it may act as a hormone, local chemical messenger, or neurotransmitter to elicit many physiological actions. Release of somatostatin from D cells in the gut is regulated by mechanisms that are both dependent on and independent of cAMP. In most cases somatostatin acts to inhibit the function of its target cells. It performs this action in part via pertussis-toxin-sensitive inhibitory guanine nucleotide-binding proteins that regulate adenylate cyclase activity. Other mechanisms may involve sites of action distal to intracellular second messenger systems .Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/44411/1/10620_2005_Article_BF01536041.pd

System for distribution and playback of multimedia content

V této diplomové práci jsem se zaměřil na návrh a vývoj aplikace zprostředkující distribuci a následné přehrávání multimediálního obsahu -- aplikace se celo-světově nazývají Digital Signage. Na základě rešerše již existujících systémů byl navržen systém vlastní. K návrhu dopomáhala metodika UML. Implementace byla provedena formou webové aplikace pod technologií HTML5. Implementováno bylo vykreslovací jádro vytvářející plynulý obraz na základě předdefinovaného scénáře, grafický editor scénáře založený na čase a síťová komunikace prvků systému pracující v reálném čase.In this master thesis I focused on the design and development of the aplication mediating distribution and subsequent playback of multimedia content - worldwide called Digital Signage. The own system was designed on the basis of research of the existing systems. UML methodology was used for the design and implementation was performed using web aplication under HTML5 technology. Rendering engine producing smooth frame rate based on predefined scenario, was implemented, as well as grafical editor of scenarios based on time and network communication of the elements working in a real time.Fakulta elektrotechniky a informatik
