Self-localization is the process of estimating the robot position exploiting noisy measurements. Since localization is a key issue for soccer playing robots, some probabilistic approaches have been developed over last years to address it. Methods based on Monte Carlo Localization (MCL) show good ability in dealing with kidnap problem, however, most of them are unstable with limited number of samples. On the other hand, Kalman filter extensions are among the best light weight estimators for position tracking. Their drawback is that they are unimodal and can't be used for global and kidnaped problems. Combining the advantages of these two approaches can lead to a valuable method. In this paper we propose a new hybrid localization method that utilizes the MCL and UKF to reach a stable, multimodal, and low weight localization method. The advantages of our method are evaluated in several experiments. © 2016 IEEE.

Different methods to generate cartoonized painterly effect on grayscale and colored images are discussed in this paper. The Concept of vector quantization is used to get the painterly effect on images. Algorithms LBG, KPE and KMCG are used to generate cartoonized painterly results. The results of applying each algorithm on images is compared based on time taken and effect generated. The results obtained by discussed methods can be incorporated in many application which are used for movie to comic conversions and digital art software.

Privacy, trust and confidentiality are the main issues of sensor layer in Internet of Things (IOT). In sensor layer, the sensing information must be transmitted from sensor node to gather node by multiple hopping. Every sensor node will be the sender and the relay node to forward the sensing information sent by other nodes. In this paper, BS embeds S+1 secret into the keys that are derived from the real identity of sensor node, to be as the private secret keys for every sensor node. One of the secret is the common secret that is owned by all sensor nodes, the rest S secretes are the random secret used for making mutual trust. Based on the secret index set and private secret keys, we propose a mutual trust method to explore the trust types and the pairing value among the sensor nodes without any negotiating process. To deny the right of malicious nodes to make trust with other nodes, we involve a group key to hash the secret index set to do making trust and pairing value mutually. Based on the trust types and the pairing values, the sensor nodes can set a secure path to deliver the sensing information to base station.

Data transfer rates for aggregated video data stream and within data centers nowadays require an electrical bandwidth up to 100 GHz. This poses big challenges for the design of proper test and measurement solutions, notably related to the acquisition of signals with such a wide bandwidth. To grant sufficient bandwidth and related sample rate, modern oscilloscopes have been using techniques based on frequency-interleaving and time-interleaving, respectively. Earlier this year, an alternative technique has been presented in a white paper [1],[2] based on which an oscilloscope that can offer an electrical bandwidth that is two times that of the adopted ADC has been launched. This result is obtained by combining the operations of a couple of time interleaved channels, each one made up of a mixer followed by an ADC. The paper presents a synchronous time interleaving technique, which can be regarded as an extension of the aforementioned technique. In fact, the proposed technique can be implemented through an architecture that includes four channels, each one including a mixer and an ADC, the latter having an input bandwidth equal to just one fourth the electrical bandwidth achieved by the system.

The aim of this paper is to investigate the effect of different burnishing strategy on a C45 steel machining. Burnishing is a well-known, cold working surface improving technology, it is usually applied for cylindrical workpiece. In the reported research a novel developed magnetic assisted ball burnishing (MABB) tool was applied which was designed for MABB machining of flat and harmonic surfaces. To increase its efficiency, different types of machining strategies were applied. After the burnishing process the machined surfaces were measured by surface roughness tester to determine the most important Rsk and Rku tribological parameters. According to the results it can be stated that all different burnishing strategies have special application areas where they can be used efficiently (e.g. sliding surface, moulding tool and after- or pre-machining for ultra-precision machining).

This work develops a CMOS active delay line for microwave CW signals. The novel active delay line is mainly based on an injection-locking (IL) technique. The delay of the input signal is linear adjusted with various injection conditions. Comparing with conventional passive or active delay lines, the proposed active delay line has a wider delay tuning range and a higher gain. The implemented CMOS delay line achieves a wide operating range of 2 ~ 2.6 GHz with very wide delay tuning range from 45~220 ns. The power consumption is lower than 7.2 mW.

Recent trends in mobile cellular networks turn towards dep.oyment of Small Cell Networks (SCNs), where the cell size gets smaller and thus the number of subscribers served in a cell will be relatively smaller and should be considered finite. However, almost works on cellular mobile networks consider an infinite population cell, resulting commonly in infinite queueing models, for which no analytical solution is available for performance measures and only numerical approximations can be obtained. In this paper, a Call Admission Control (CAC) in a finite population micro-cell operating in a SCN, with retrials of blocked new calls, impatience of subscribers and multiple guard channels dedicated to handoff calls, is proposed. For the numerical computation of the steady-state probabilities of the corresponding continuous time Markov chain (CTMC), an efficient algorithm giving automatically the infinitesimal generator is developed, and various performance measures are established in network parameters and stationary probabilities. The guard channels number and retrials effect on the network performance in terms of blocking probability (for new calls and retrials) and dropping probability (of handoffs) is also carried out via experimental results.

Due to increasing number of internet users, popularity of Broadband Internet also increasing. Hence the connection cost should be decrease due to Wi Fi connectivity and built-in sensors in devices as well the maximum number of devices should be connected through a common medium. To meet all these requirements, the technology so called Internet of Things is evolved. Internet of Things (IoT) can be considered as a connection of computing devices like smart phones, coffee maker, washing machines, wearable device with an internet. IoT create network and connect "things" and people together by creating relationship between either people-people, people-things or things-things. As the number of device connection is increased, it increases the Security risk. Security is the biggest issue for IoT at any companies across the globe. Furthermore, privacy and data sharing can again be considered as a security concern for IoT. Companies, those who use IoT technique, need to find a way to store, track, analyze and make sense of the large amounts of data that will be generated. Few security techniques of IoT are necessary to implement to protect your confidential and important data as well for device protection through some internet security threats.
