The quality of the inductor is insured due to a differential negative resistor connected at the input of the inductor. Single ended active inductors present non-linear effects hence the need of using differential topology to reduce them and avoid the waste of biasing current. The simulated differential active inductor has a very high quality factor of 1340 and operates at 1.34 GHz. It can be easily tuned in frequency which is suitable for GSM 1800MHz applications.","PeriodicalId":405923,"journal":{"name":"2015 International Conference on Electrical and Information Technologies (ICEIT)","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129564167","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 mixed reality is promised to be a new technology to create a virtual environment where the learner is an actor by interaction with virtual objects. The objective is to establish a virtual laboratory that all tools and products can be manipulated by learners like in real practical work. This virtualization can also solve the safety problems and may reduce the risk of some experiments: nuclear, chemical, etc. Another interesting benefit is the reduction of the investment on real hardware (locally or remotely). We propose an approach for developing integrated E-learning systems, helping to carry out the practical work by the distance learner based on an augmented reality system.","PeriodicalId":405923,"journal":{"name":"2015 International Conference on Electrical and Information Technologies (ICEIT)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115886253","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}

It is shown that the OTS are equi-powered, equi-spaced and position orthogonal. However, in special cases we can find that required conditions to achieve optimal pilot design are not satisfied, this means the optimum pilot is unachievable. In this paper, an algorithm is proposed to achieve suboptimum pilot design under time varying channels. To offer high throughput gains, we propose an adaptive pilot scheme in order to optimally use pilot tones over time varying channels.","PeriodicalId":405923,"journal":{"name":"2015 International Conference on Electrical and Information Technologies (ICEIT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129780978","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}

Our model includes many high-order effects to achieve accuracy for most physical phenomena like the avalanche (breakdown characteristics), Webster, Charge storage, Self-heating and Early effects. The validity and the accuracy of the model are assessed by comparing the simulations with the DC measurements which are Gummel plots and Ic-Vce characteristics.

For this kind of systems, not only the correctness of a computed result but also the strict adherence to timing requirements of computation is essential to avoid any kind of damage. To react to unpredictable, arbitrary hardware faults suitable error detection mechanisms have to be applied. The caused error itself and the detection and correction have great impact on the system's timing behavior. To still keep the real-time requirements, the used scheduling algorithm has to ensure maximum flexibility to disturbances of the timing. The group of Proportionate Fair (Pfairness) multicore scheduling algorithms has been proven to create an optimal schedule in polynomial time. The contribution of this paper is a Pfair-based algorithm that uses tight coupling between the error detection mechanisms and the scheduler of the real-time operating system to establish a loop-back connection.","PeriodicalId":405923,"journal":{"name":"2015 International Conference on Electrical and Information Technologies (ICEIT)","volume":"52 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133769499","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}

In order to understand the nature and behavior of such attacks, many classification schemes and taxonomies to MANET attacks have been proposed. This paper proposes a new taxonomy to MANETs attacks. The taxonomy is aimed to provide a consistent means of classifying attacks, as well as allowing previous knowledge to be applied to new attacks and providing a structured way to view such attacks. The taxonomy is based on attack attributes. Every attack is characterized by a unique vector of attribute values, where each attribute defines a specific attack property which may have different values. The taxonomy uses six attributes; the legitimacy of attacking node/s, the number of nodes participating in the attack, MANETs vulnerabilities utilized by the attack, the network resources exploited by the attacking node/s, the targeted victim and finally, the network security service compromised by the attack. The analysis of some well known attacks shows the capability of the proposed taxonomy in describing and categorizing these attacks as taxonomy vectors.","PeriodicalId":405923,"journal":{"name":"2015 International Conference on Electrical and Information Technologies (ICEIT)","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131165316","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}

Therefore, it becomes a challenge to extend sensor nodes' life while maintaining the network overall performance. Mobility of the network sensor nodes may accelerate energy depletion and increase the need for effective energy-conserving WSN routing protocols. In this paper, we present a novel energy-saving routing scheme for mobile WSN. Our proposed routing algorithm adapts dynamically to network node's energy-level. For data transport to the network base-station (network sink), it selects only nodes that balance the mobile WSN energy saving distribution. Simulation experiment was conducted to obtain relationships between various algorithm performance measures and network parameters such as: network number of sensors, sensors' message memory/buffer size, message arrival rate, number of duplicates allowed, and transmission/reception distance. The results suggest that the proposed MSN routing algorithm gives around 10% gain of throughput, reduces message duplicates by eight times, eliminates congestion to 0% in average, and increases nodes' life, e.g., First Node to Die (FND), by twofold with a non-significant increase of message delay and jitter.","PeriodicalId":405923,"journal":{"name":"2015 International Conference on Electrical and Information Technologies (ICEIT)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129238874","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}
