Demand Forecast of 700 MHz Frequency Spectrum for LTE Mobile Broadband Services

Frequency spectrum of 700 MHz is one of many candidates for LTE service establishment in Indonesia. On the beginning, this spectrum is used for analogue TV broadcasting. After the digital switchover period, there are 108 MHz bandwidth left behind because of the digital broadcasting transformation which later is called digital dividend. On this research, a certain growth model is used to demand forecast the frequency spectrum needed for this digital dividend LTE. The purpose of this paper is to calculate how much spectrum needed to deliver the LTE services within certain paramete

Reducing latency when using Virtual Reality for teaching in sport

Latency is a frequently cited shortcoming of Virtual Reality (VR) applications. To compensate for excessive latency, prediction mechanisms may use sophisticated mathematical algorithms, which may not be appropriate for complex virtual teaching applications. This paper suggests that heuristic prediction algorithms could be used to develop more effective and general systems for VR educational applications. A fast synchronization squash simulation illustrates where heuristic prediction can be used to deal with latency problems

Pedagogical Feedback for Computer-based Sport Training

Feedback in Computer-based Sport Training (CBST) may be synthetically designed to allow athletes to practise in a more effective way and enhance their skill acquisition. Little research has integrated pedagogic theory and instructional design with the design of feedback in CBST. To bridge this gap, the paper presents the design of pedagogically-informed feedback for the implementation of a CBST system. The heart of the design is to generate feedback based on the athletes’ achievement of their intended training outcome. The pedagogical feedback system measures athletes’ performance and compares it with the given training outcomes. The system then identifies the performance’s gap and generates feedback to reinforce better performance. A Counterbalanced experiment asked student rowers (N = 8) to explore the differences between the pedagogical feedback system and their current feedback system (Sean-Analysis). Pedagogical feedback was at least as good as Sean-Analysis with respect to the level of satisfaction of the athlete. Overall, it can be concluded that the pedagogical feedback appears to be a good model for generating feedback in CBST

REDUCING LATENCY IN A VIRTUAL REALITY-BASED TRAINING APPLICATION

Overall latency is the elapsed time from input of human motion to the immediate response of the input in the display. Apparently, latency is one of the most frequently cited shortcomings of current Virtual Reality (VR) applications. To compensate latency, previous prediction mechanisms insert a complex mathematical algorithm, which may not be appropriate for complex virtual training applications. More complex VR simulations most likely will impose greater computation burdens and resulted in the increase of latencies. In order to overcome latency problem, this research is an attempt to suggest a new prediction algorithm based on heuristic that could be used to develop a more effective and general system for virtual training applications. The heuristic-based predictor provides a platform to utilize the heuristic power of human along with the algorithmic power, geometry accuracy of motion-planning programs and biomechanical laws of human. Heuristic algorithm is an important module widely used for humanoid robots and avatars in VR systems. However, to the best of the researcher's knowledge, the heuristic approach has not been used as a single prediction algorithm for compensating latency in virtual training systems. In order to find out whether the new prediction algorithm is acceptable and possibly could reduce latency, a fast synchronization squash-game simulation was selected as a study source. This research analyzed the latencies of all subcomponents of this system and designed prediction algorithm that allows high-speed interaction. In measuring the performance on various prediction methods, this research also makes a comparison in real tasks among 1) the heuristic-based prediction, 2) the Grey system prediction and 3) the one without prediction using different sample rates. Findings indicated that heuristic-based algorithm is an accurate prediction method to compensate latency in virtual training. Apparently, heuristic-based prediction and Grey system prediction are significantly better than the one without prediction. When heuristic-based prediction and Grey system prediction were compared, heuristic-based prediction was in fact a better predictor. Overall findings indicated that heuristicbased prediction is efficient, robust and easier to implement

Characteristics of Heavy Metals Adsorption Cu, Pb and Cd Using Synthetics Zeolite Zsm-5

It is generally known that zeolite has potential for heavy metal adsorption. The objectives of this study were to synthesize and characterize zeolite ZSM-5 and to figure out the adsorption capacity of zeolite ZSM-5 for heavy metals of Cu2+, Pb2+ and Cd2+. Characterization of zeolite ZSM-5 included some variables i.e. crystal structure (XRD), morphology (SEM), specific surface area and total pore volume (N2 physisorption). Adsorption capacity of zeolite ZSM-5 was analysed using a batch system with heavy metals of Cu2+, Pb2+ and Cd2+ in various concentrations (50, 100, 150, 200 and 250 ppm) with contact times 30, 60, 90, 120 and 250 minutes. Adsorption data was calculated by Langmuir and Freundlich isotherm. The results showed that the maximum adsorption capacity of zeolite ZSM-5 against heavy metals of Pb2+, Cu2+, and Cd2+, were 74.07, 69.93 and 60.24 mg g-1, respectively. These indicated that synthetic zeolite ZSM-5 had potential to adsorb heavy metals. The results also suggested that the adsorption capacity was affected by the pore size of zeolite, negative charge of zeolite, diameter of hydrated and electronegative ion
