These type of SLAs are suggested for all types of traffic from best effort to QoS constraint applications. In access networks, where these SLAs are prevalent, shared memory switches is a common architecture. Thus, dimensioning and management of shared memory queues for multiple priorities each with two levels of guarantees becomes an interesting challenge. We present a simple analysis of a multipriority multi discard level system controlled by a buffer occupancy threshold policy aimed at assuring service level agree- ment compliance for conforming (i.e., committed) traffic, and performance maximization for non-conforming (i.e., excess) traffic. Our analysis shows how the different system parameters: total buffer size, threshold position, and offered load control performance for the committed and excess traffic. Our results allow assuring high service level agreement compliance for conforming traffic, and performance maximization for non-conforming traffic.","PeriodicalId":142814,"journal":{"name":"2006 IEEE 24th Convention of Electrical & Electronics Engineers in Israel","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133894734","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Optimal requantization aims to find a set of new step-sizes that achieve the target bit rate while introducing minimal distortion. Since the state of the art H.264 standard coder constrains requantization by limiting the amount of change in the quantization step-size from one macroblock to the next, the common Lagrangian optimization approach cannot be applied. We propose a solution to this dependency problem by extending each Lagrangian iteration with a constrained dynamic programming stage. Further, in order to reduce the computational load of evaluating the rate and distortion at each macroblock for multiple step-sizes, we suggest analytic models that can be applied for this purpose. The developed models are suitable for requantization and are matched to the context-adaptive entropy coding used in H.264. The proposed algorithm performs the requantization in the compressed domain and currently supports inter coded frames only. It reduces the run-time by a factor of 4, as compared to the full exhaustive optimization, and achieves up to 1[dB] gain in PSNR, as compared to a simple one-pass algorithm.","PeriodicalId":142814,"journal":{"name":"2006 IEEE 24th Convention of Electrical & Electronics Engineers in Israel","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132450658","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The application can benefit from relaxed bandwidth limits and wider Doppler frequency deviations. Circuit feature sizes are scaled down with the wavelength resulting in smaller and better integrated circuits than could be achieved at lower frequencies. Shorter wavelengths also enable higher spatial resolution given the same aperture. This may be irrelevant for a single sensor but could be utilized when many sensors are deployed to cover a large area in applications collectively known as \"Smart Dust\". Since mm-wave interconnects pose significant challenges in assembly precision, materials and therefore cost, a complete integration of all such circuits, interconnects and antenna within a single MMIC die lowers product cost and enables diverse applications. The resulting sensor can be used as a proximity and range detector and is aimed at low cost applications. Target security applications include perimeter control, intruder detection and identification. Machine vision, RFID and obstacle avoidance applications could also utilize such a sensor. This paper discusses design tradeoffs, implementation and results of one of several prototype sensor front-end devices implemented in GaAs MMIC technology.","PeriodicalId":142814,"journal":{"name":"2006 IEEE 24th Convention of Electrical & Electronics Engineers in Israel","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128830607","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The classic method, utilized in most PWM converters, is to place the inductor in a path that has a non-zero average current. Such inductors are referred to here as \"DC inductors\". In contrast, inductors that operate with zero average current are denoted \"AC inductors\". The theoretical analysis carried out in this paper compares the small signal response of the current in the DC and AC inductors as a function of various system parameters, such as input and output voltages and duty cycle, in the case of the DC inductor, and frequency in the case of the AC inductor. The analysis was supported by large and small signal model developed in this study and verified against analytically derived large and small signal equations. The small signal current response was derived by applying average models. The analytical derivations and simulations of this study were verified experimentally. Good agreement was found between the theoretical predications and the analytical results. Based on the results of this study one can conclude that \"AC inductor\" based topologies are optimal for current sourcing applications, such as battery chargers, where differences between the average input and output voltages are expected to exist and develop over time.","PeriodicalId":142814,"journal":{"name":"2006 IEEE 24th Convention of Electrical & Electronics Engineers in Israel","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123408839","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
