Abstract

Support vector machine is a popular method in machine learning. Incremental support vector machine algorithm is ideal selection in the face of large learning data set. In this paper a new incremental support vector machine learning algorithm is proposed to improve efficiency of large scale data processing. The model of this incremental learning algorithm is similar to the standard support vector machine. The goal concept is updated by incremental learning. Each training procedure only includes new training data. The time complexity is independent of whole training set. Compared with the other incremental version, the training speed of this approach is improved and the change of hyperplane is reduced. DOI: http://dx.doi.org/10.11591/telkomnika.v10i6.1445

Abstract

Moment is a useful tool in character and drawing recognition. As the moment computation is time-consuming, the main aim in this area is to develop a fast algorithm. The commonly-used method is the discrete Green’s theorem, which transforms the double summation into a summation on region contour. An improved discrete Green’s theorem proposed in this paper, which removes the constraint on parity pairing, thus extends its validity in applying the algorithm to complex regions. The contour tracing is fulfilled by a boundary-tracing-automation, and the central moments for graphical primitives are computed by one-pass scanning algorithm, the calculation of the moment is greatly simplified DOI : http://dx.doi.org/10.11591/telkomnika.v12i5.5099

Abstract

The idea of replacing the old lighting system with energy-efficient ones has been given excessive attention, particularly in the territorial and Arabic world. This move is significant for its helpful effects on both the economy and the environment, especially in Iraq which smarts from light-related problems. It correspondingly aids the light distribution offices as it will save them from several light generation troubles and their effects on the hours of electrical power supply. The light consumers will also benefit from reduced bills due to approximately 50% reduction in power consumption by the energy-efficient system. The energy-efficient lighting system has replaced the traditional technical lighting owing to its energy saving capability and environmental friendliness. These problems would enhance the use of efficient energy programmer to reduce energy consumption as the world switches to the use of renewable energy. This study presents the use of modernized lighting system with an emphasis on its economic and environmental benefits. The results are applied by MATLAB version17b prototypical is built to evaluate the behavior of smart lighting street technology and renewable energy to reduce cost and energy consumption. During the study, 100 modernized LED electric lamps of 150W capacity were used to replace 100 high pressure sodium (HPS) lamps of 400W. The economic cost of the replacement was calculated based on the price of the LED lamps compared to those of the HPS lamps. The environmental impact was determined by calculating the global cost of the electrical energy consumed by the LED lamps compared to those consumed by the HPS lamps in Iraq.

Abstract

This paper presents a novel model to evaluate the power output of a building integrated photovoltaic system (BIPVS) operating in the Andean Range.  The Optimal Power Flow (OPF) model optimizes the power output of the BIPVS within an electrical system without violating operational limits.  The model is validated with the experimental performance of a 6 kW BIPVS installed in Bogota, Colombia. The meteorological data affect the power flow. The model is evaluated under sunny and rainy days to characterize the photovoltaic array performance. The results showed that the AC PV-energy generation was 5,904 kWh/year for 2017 and that there is a correlation factor of 99.87% between the experimental power flow and the proposed model.

Abstract

Real time multi-channel sliding correlation processing is widely applied in underwater communication system or underwater positioning system. The traditional implementation in FPGA always employs parallel method which reduces the design work, however wastes considerable FPGA resources. This paper described a new kind of SOPC structure which based on AVALON bus, taken NIOS CPU as system controller, DMA used for accurate data transmission between computing units. This kind of time-multiplexed processing structure improved controlling flexibility and saved FPGA resources. System stability was proved by lake experiments. DOI: http://dx.doi.org/10.11591/telkomnika.v11i3.2307

Abstract

The traditional regenerative braking control strategies for hybrid electric vehicle just only considers to ensure motor to work along with the battery/motor joint optimal efficiency curve, but not consider CVT efficiency, yet in fact that the CVT efficiency varies with the operating condition between 70% and 95% variation and can not be neglected. Based on the analysis of the relationship among the synthesis efficiency and the efficiency of the NiMH battery, ISG motor and CVT, the battery/motor/CVT joint high efficiency are calculated, then the joint high efficiency optimum working curve is drawn, finally the regenerative braking control strategy adopted with the joint high efficiency optimum working curve is proposed. Compared to the offline simulation and HIL test results adopted with the battery/motor joint high efficiency optimum working curve, the motor average generating efficiency increases by 2.23%, braking energy recovery rate increases by 4.09% through offline simulation, and the average generating efficiency increases by 1.13% through HILS test. Both results show that the proposed regenerative braking control strategy can realize the battery, motor and CVT to work with joint high efficiency which fatherly enhances braking energy recovery rate under guaranteeing entire vehicle braking security condition.

Abstract

According to the non-stationary property of vibration signal, the vibration signal is decomposed by empirical mode decomposition (EMD). And this method is applied to study the remanufacturing level of engine. Based on the decomposition of vibration signal, correlation coefficient is introduced to study the correlation between IMF (Intrinsic Mode Function) components and original signal, and dynamic structure of IMF components is analyzed by correlation dimension. In order to study the remanufacturing level of engine, correlation coefficient and correlation dimension are considered in the function of IMF, and an index of vibration intensity is proposed. A corresponding relationship is established between remanufacturing level and vibration intensity. This method has been proved that the running state of engine can be reflected by vibration intensity, and this index can be used to evaluate the remanufacturing level of engine. DOI : http://dx.doi.org/10.11591/telkomnika.v12i1.3896

Abstract

Small devices that can sense and collect data from the surrounding environment have been produced with the rapid development of wireless technology and digital electronics. As a result, a wireless sensor network (WSN) was constructed from these sensor devices to send collected data to the base station for monitoring and analysis. This paper provides an overview of WSN, as well as its architecture and applications.

Abstract

Cyber information is the solution for e-commerce, in this study we investigated the LAN is needed and seek confirmation of the decision to use the method Red-Black Tree in forming binary search tree. Given the status of the wireless modalities and development of RAID, this study used a Bayesian tool in controlling identifier-locator split (palmate). In addition, to verify that Boolean logic and the model checking can collude to address this problem. In this paper, we verify that rasterization can be made strong, cooperative, and adaptive. Furthermore, we concentrated this study can be made so that IPv6 embedded, scalable, and highly-available. Our design for investigating encrypted algorithms is dubiously promising. Finally, we introduced an analysis of journaling file systems (Palmate), which we used to validate that local-area networks and replication are often incompatible.
