DXR: towards a billion routing lookups per second in software
No full textCan a software routing implementation compete in a field generally reserved for specialized lookup hardware? This paper presents DXR, an IPv4 lookup scheme based on transforming large routing tables into compact lookup structures which easily fit into cache hierarchies of modern CPUs. DXR supports various memory/speed tradeoffs and scales almost linearly with the number of CPU cores. The smallest configuration, D16R, distills a real-world BGP snapshot with 417,000 IPv4 prefixes and 213 distinct next hops into a structure consuming only 782 Kbytes, less than 2 bytes per prefix, and achieves 490 million lookups per second (MLps) in synthetic tests using uniformly random IPv4 keys on a commodity 8-core CPU. Some other DXR configurations exceed 700~MLps at the cost of increased memory footprint. DXR significantly outperforms a software implementation of DIR-24-8-BASIC, has better scalability, and requires less DRAM bandwidth. Our prototype works inside the FreeBSD kernel, which permits DXR to be used with standard APIs and routing daemons such as Quagga and XORP, and to be validated by comparing lookup results against the BSD radix tree
Development of the system for determining the wear of the cutting tool with the camera
Get PDFV diplomskem delu obravnavamo zelo pomembno področje odrezovanja. Pri procesih odrezovanja prihaja do obrabe orodij. Za doseganje visoke kakovosti končnih izdelkov in znižanje stroškov izdelave je potrebno spremljati obrabo orodja. V diplomskem delu je kratek pregled vzrokov in posledic nastanka obrabe orodja. S spremljanjem obrabe orodja lahko dosegamo visoke kakovosti izdelkov. Za določevanje obrabe orodja s klasičnim določevanjem je potrebno izpeti ploščico, s tem pa izgubimo pozicijske tolerance in čas, ko obdelovalni stroj ne obratuje. Zato smo se odločili razviti prototipni sistem za sprotno določevanje obrabe rezalnega orodja s kamero na obdelovalnem stroju. Prototipni sistem deluje na podlagi strojnega vida, kamera zajema sliko, nato se s pomočjo programske opreme Labview izvede analiza slike. Ta nam poda vrednosti obrabe orodja. Sistem smo testirali v laboratoriju LABOD in razbrali, da so rezultati meritve sistema v primerjavi s klasičnim merjenjem podobne z pogreškom na tretjem decimalnem mestu ter ugotovili, da sistem zanesljivo deluje.In the thesis we consider a very important field of cutting. In cutting processes it comes to tool wear. To achieve high quality finished products and to reduce production costs, tool wear must be monitored. In the thesis is a brief overview of the causes and consequences of wearing tools. By detecting tool wear we can achieve high quality products. To determine the wear of the tool with classical determination, it is necessary to remove the tool, thus losing the position tolerances and the time when the machine does not operate. Therefore, we decided to develop a prototype system for real-time determination of the wear of the cutting tool with the camera on the machine. The prototype system works on the principle of machine vision, the camera captures the picture, then an image analysis is performed using Labview software. Image analysis gives us the tool wear values. The system was tested in the laboratory of LABOD and found that the measurements of the system by comparing classical measurement are the same with a smaller deviation so we have found that the system works reliably
Art therapy for people with intellectual disabilities and emotional behavioral disorders
Get PDFIntellectual disabilities (ID) are disorders characterised by under-average intellectual functioning and reduced adaptive functions. ID are affecting individual perceptions, ways of thinking, interactions, emotions and behaviour. According to a level of deficit persons with ID are categorised at mild, moderate, severe and profound intellectual disability. People with ID can be included in personalised or special education programs. Most people with ID have no access to the labour market and are involved in various work activities within the centres. They receive a symbolic payment for their work. They live with their parents or in special homes for people with ID, accommodation units, housing communities, or in homes for the elderly. Emotional and behavioural disorders often occur in people with ID. Emotional and behavioural disorders (EBD) are characterised by aggressive, auto-aggressive and delinquent behaviour. The occurrence of EBD is influenced by various biological, ecological, social and personality factors.
Arts therapies, as a subtype of art therapy, turned out to be useful in dealing with people with ID associated with EBD. The goal of arts therapies is to improve the quality of people's lives, which includes many areas of life for an individual. For people with ID, it is particularly effective, because it offers communication along the other path and offers the possibility of developing its own identity through the development of the painting style. Arts therapies is characterised by the triangular relationship which includes a participant, an art product, and a therapist. Their mutual relationship is significant. Arts therapies has certain phases and structure of therapeutic meetings. It can be individually, collectively or combined. Different art therapy techniques and activities are used according to the participant's characteristics and goals that we want to achieve. Knowing and adapting art materials is essential, primarily when working with people with ID. It is crucial to know the development of artistic expression and the specificity of the development of artistic expression in persons with ID.
In the empirical part, we used three case studies to determine the impact of arts therapies in the treatment of people with ID associated with EBD. The influence of arts therapies was observed in the areas of self-image, autonomy, self-initiative and perseverance, communication, social interaction and specific behavioural areas specific to individual EBD. In the study were involved three people with moderate ID associated with mild EBD, with between 18 and 37 years of age. In determining the initial and final condition, we used the standardized Adaptive Behavior Scale form The American Association for Mental Deficiency (AAMD) (Igrić in Fulgosi-Masnjak, 1991) and questionnaire customised by 'Evaluation List of Aid with Art' (Evalvacijski list Pomoči z umetnostjo) from the author E. Bizjak (2007). The scales and the questionnaires were filled by a professional who personally knows participants. The research showed that arts therapies has positive effects on participants, especially in the areas of challenging behaviour, autonomy and self-image. Arts therapies also had a positive impact on the areas of self-initiative and perseverance, social relations and communication. It has been concluded that for significant changes in this population, it would be necessary to carry out arts therapies for a more extended period, at least two years or more

ALTERNATIVE SOURCES OF ENERGY : WAVE ENERGY
No full textAlternativni izvori energije su važni zbog njihovog manjeg utjecaja na okoliš. Energija valova je jedan oblik alternativnih izvora energije koja ima velik potencijal. Postoje različiti sustavi iskorištavanja energije valova za proizvodnju električne energije. Većina sustava je u eksperimentalnoj fazi zbog kompliciranog postupka i visokih troškova razvoja sustava.Alternative energy sources are important due to their smaller environmental impact. Wave energy is one form of alternative energy sources which has a great potential. There are different types of systems which use wave energy to produce electrical energy. Most of systems are in experimental stage due to complicated procedure and high development costs

Incidence of femoral and popliteal artery restenosis in patients treated with drug coated balloons in Clinical Hospital Center Rijeka
No full textPeriferna arterijska bolest (PAB) je vaskularno oboljenje koje rezultira suženjem ili okluzijom arterija što dovodi do smanjenja kvalitete života oboljelih, povećanog rizika od amputacija ekstremiteta ali i smrti, dok se broj oboljelih mjeri u milijunima. U slučaju sumnje na PAB, pacijenta se podvrgava kliničkom pregledu i objektivnim kliničkim testovima poput ispitivanja ABI indeksa (engl. ankle-brachial index) te laboratorijskim pretragama. U slučaju potvrđene kliničke sumnje, pristupa se slikovnoj dijagnostici kao što je angiografija kompjutoriziranom tomografijom (CTA), digitalna subtrakcijska angiografija (DSA) i angiografija magnetskom rezonancijom (MRA) kako bi se utvrdila lokacija i težina oboljenja. Nakon dijagnosticirane PAB, odluka o daljnjem liječenju se donosi na konziliju liječnika koji najčešće uključuje vaskularnog kirurga, intervencijskog radiologa i neurologa, a po potrebi i liječnike specijaliste iz drugih područja medicine. Cilj: Utvrditi učestalost restenoze femoralne i poplitealne arterije u razdoblju praćenja od godinu dana kod bolesnika liječenih u Kliničkom bolničkom centru Rijeka (KBC Rijeka) nakon liječenja balonima obloženim lijekom (DCB). Drugi cilj ovog rada je usporediti dobivene rezultate s rezultatima objavljenim u IN.PACT SFA multicentričnoj randomiziranoj studiji. Na taj način ćemo procijeniti uspješnost obavljenog postupka u KBC Rijeka u odnosu na rezultate drugih europskih i svjetskih centara. Materijali: Pretraživanjem baza podataka Kliničkog bolničkog centra Rijeka (ISSA i IBIS), retrospektivno su prikupljeni podaci o pacijentima kojima je obavljena perkutana transluminalna angioplastika (PTA) površinske femoralne i poplitealne arterije DCB metodom od 1. siječnja 2020. do 31. prosinca 2020. godine. Rezultati: U analizu je uključeno 79 bolesnika. Aritmetička sredina dobi bolesnika iznosi 68,32 godina (min 39, max 87, st.dev.8,8). Raspodjela bolesnika prema spolu je 20 pacijenata ženskog spola, odnosno 59 muškog. Pojavnost restenoze nakon provedenog liječenja je 20,25% (16 osoba), dok kod 79,75% (63 osobe) nije došlo do pojave restenoze u jednogodišnjem periodu praćenja. Zaključak: Rezultati provedenog istraživanja u KBC Rijeka pokazuju minimalno odstupanje od podataka objavljenih u IN.PACT SFA studiji u vidu učestalije pojavnosti restenoze kod pacijenata liječenih u našoj ustanovi u odnosu na IN.PACT SFA studiju (odstupanje za 2,45%). Činjenica da je naša studija provedena na manjem uzorku te da u obzir nisu uzete i druge podležeće bolesti kod bolesnika kao ni dužina i stupanj stenoze i/ili okluzije mogao bi biti razlog navedenim minimalnim odstupanjima između dvije studije. Zaključno možemo reći da su uočena odstupanja između dvije studije minimalna, no svakako je potrebna daljnja detaljnija analiza koja bi uključivala veći broj bolesnika te standardizaciju uključnih i isključnih kriterija kako bi mogli donijeti precizniji zaključak o uspješnosti metode.Peripheral arterial disease (PAD) is a vascular disease that results in the narrowing or blockage of arteries, which leads to a decrease in the quality of life of patients, an increased risk of limb amputations and death, while the number of patients is measured in millions. In case of suspicion of PAB, the patient undergoes a clinical examination and objective ABI index measurement (ankle-brachial index), as well laboratory tests. In case of confirmed clinical suspicion, imaging tests such as computed tomography angiography (CTA), digital subtraction angiography (DSA) and magnetic resonance angiography (MRA) are used to determine the localization and severity of the disease. After PAB is diagnosed, the decision on further treatment is made at a doctor's council, which usually includes a vascular surgeon, an interventional radiologist and a neurologist, and if necessary, doctors specialized in other fields of medicine. Objective: To determine the frequency of femoral and popliteal artery restenosis over a period of one year in patients treated at the Clinical Hospital Center Rijeka (CHC Rijeka) after treatment with drug-coated balloons (DCB). Another goal of this paper is to compare the obtained results with the results published in the IN.PACT SFA multicenter randomized study. In this way, we will evaluate the success of the procedure performed at CHC Rijeka in relation to the results of other European and international centers. Materials: By searching the databases of the Rijeka Clinical Hospital Center (ISSA and IBIS – integrated hospital information system), data were collected retrospectively on patients who underwent percutaneous transluminal angioplasty (PTA) of the superficial femoral and popliteal arteries using the DCB method from January 1st, 2020 to December 31st of 2020. Results: 79 patients were included in the analysis. The arithmetic mean of the patient's age is 68.32 years (min 39, max 87, st.dev.8.8). The distribution of patients by gender is 20 female patients and 59 male patients. The occurrence of restenosis after treatment was 20.25% (16 people), while 79.75% (63 people) did not experience restenosis in the one-year follow-up period. Conclusion: Results of the research performed at CHC Rijeka show a minimal deviation from the data published in the IN.PACT SFA study in the form of a more frequent occurrence of restenosis in patients treated in our institution compared to the patients included in IN.PACT SFA study (a deviation of 2.45%). The fact that our study was conducted on a smaller sample and that other underlying diseases of the patients as well as the length and degree of stenosis or occlusion were not considered, could be the reason for the earlier mentioned minimal deviations between the two studies. In conclusion, we can say that the observed deviations between the two studies are minimal, but a further, more detailed analysis that would include a larger number of patients and the standardization of inclusion and exclusion criteria is necessary in order to make a more precise conclusion about the success of the method
