A broadband PIFA antenna that operates in the 800-970 MHz and 1.5-5.9 GHz bands with VSWR less than 3 is proposed for wireless communications terminals. This wideband is enough to cover many of the most important mobile communications services around the world such as GSM 850/900, DCS, PCS, UMTS, WiFi, Bluetooth, WiMAX, and the major part of the LTE bands. Antenna volume of 4×2×1 cm3 is within acceptable limits for different mobile terminals including portable handheld devices and embedded WLAN antennas. Besides its wideband characteristic, the proposed antenna exhibits adequate gain and radiation patterns, and has the advantages of any PIFA antenna such as low SAR and stable tuning.

A graph is said to be planar if it can be drawn on the plane with vertices as different points and edges as continuous curves that only intersect its vertices. An embedding of a graph is said to be primitive if its edges are primitive segments. A recent conjecture is that all planar graphs with n vertices have a primitive embedding in a square grid of side O(n). It is known that trees have that type of embedding. A smallest primitive embedding is that in which the square grid has side as small as possible. In this work we present some results about the smallest primitive embeddings for trees, outerplanar graphs, and planar graphs with few vertices, as a computational approach to give evidence that the above conjecture might be true.

In this article, a methodology to obtain the characterization of the standard cell library called SXLIB is presented, this library is available within Alliance tools. The later proposal is developed based on the spreading analysis that the signal has throughout each cell, this with the objective of obtaining a delay time according to the technology of the manufacture's receiver. This characterization technique can be used with any set of standard cells, for a manufacturing technology that differs by the default one used by Alliance, then, the results of the new characterization are presented of the specified library SXLIB. The importance of knowing the spreading time of the signal, is due to the required time to include the necessary delays in the design of self-timed structures. This is, one of the key phases of the design and synthesis process, expressed in structural language VHDL that generates Alliance tools. Throughout this phase, the designer will prove that the IC works under the desired behavior, in form (logic operation) as in time (maximum and minimum delays, maximum work frequencies, etc.). That is because the obtained results from using the characterized library represent a key point in the design of self-timed structures.

The GRID computing paradigm consists of multiple heterogeneous distributed clusters connected by heterogeneous network interfaces. One advantage of this paradigm is to analyze massive amounts of data employing computing resources at different geographic places with different platforms. However in order to harness the power of those resources, many problems must be solved. In this work we deal with the problem of fault tolerance on heterogeneous computer systems. Our proposal aims to ease the process of recovery when system failures are detected at runtime avoiding the necessity for application restarts. Our proposal works through a set of services that performs transparent task migration over the computing nodes, hiding the complexity related with error handling when a hybrid programming model based on Open MPI and OpenCL is employed.

In this work, a design for a high G sensor is proposed demonstrating a novel transduction technique that can be fabricated with a standard 0.5μm CMOS technology. No additional modifications to the fabrication steps are needed to achieve a MEMS (Micro-Electro-Mechanical System) accelerometer. The proposed system uses Multiple Input Floating-gate MOS transistors (MIFGMOS) as capacitive transduction elements. A variable capacitance is configured between fingers attached to the proof mass as one plate, and to the fixed structure, as the other plate. When acceleration is applied, this results in a modification of the floating gate voltage of the FGMOS, with a corresponding current change that can be correlated to acceleration. Also, a mechanical study was made with a given geometry structure, as well as an electrical analysis of the FGMOS transistor performance. Finally, a layout is proposed for the accelerometer system. Therefore, it is demonstrated that this design can be fabricated with the desired specifications through a standard CMOS technology. Additionally a novel transduction alternative compared to that used in conventional designs is demonstrated.

With the increasing development of Web services (WS) it is necessary to use tools capable of providing better and more efficient search and classification mechanisms. Bringing to users the facility to select a service or a set of services that satisfy the specified functional requirements of an application. However, the existing methods for classification and searching are developed with similar aims, but they use different input elements for its running, making them mutually incompatible among all approaches developed, avoiding their reusability. Therefore, we propose the representation of WS operations as N-ary trees for semantic and/or structural comparisons. Allowing independent comparison algorithms use N-ary trees as the same input, to making them compatible. Allowing Make more specific and focused algorithms, which can separate the semantic part of an operation with its structure by using a unique input, either they have semantic annotations or not because our N-ary trees have all necessary information for semantic or structural comparisons. Additionally, we propose to process service operations as tree structures and represent them using RDF - a language for knowledge representation - to execute inferences and get semantic annotations. This semantic representation will specify easily the relation between composite variables names and the names of their primitive variables which are contained in a WS operation. Generating RDF serializations that easy the automatic extraction of semantic relations between the variables names of an operation and allowing to link variables names with their semantics defined in a different RDF resource. Generating automatic documentation for web services operations by using the information of semantic repositories.

In this work, a Scale-Invariant Feature Transform method, together with a K-means clustering is used in order to find regions of interest (ROI's) in mammograms. This paper focuses on presenting a tool that can improve the search of suspicious areas that contain abnormalities, leaving the final decision to the radiologist. The methodology is divided into three sections: first, a pre-processing step that consist in acquiring image and reduction its size erasing the background leaving only the breast area and eliminating noise. The second step is to improve the image quality through image thresholding and histogram equalization limited contrast (CLAHE). Last step of the methodology is the location of regions of interest in the image and is done using Scale-Invariant Feature Transform (SIFT) as the main tool and is complemented with Binary Robust Independent Elementary Features (BRIEF) to find descriptors and as classifier K-Means Clustering. Finally in the results are presented the location of ROI's and they are compared with the position of abnormalities diagnosed by the Mammographic Image Analysis Society.

This manuscript presents the research and development of a software that help deaf-mute communication by identifying the position of the fingers of the hand with 5DT gloves. The sign language is adopted by nearly all people with hearing deficiency, making it their main form of communication, but this communication is only successfully achieved if all the participants of the conversation are familiar with the sign language. The goal is to be able to translate hand signs into words and phrases with the possibility to send audio signals to allow deaf-mute users to communicate to people not familiar with the sign language. The recognition of hand gestures is accomplished using a neural network tested using five different training algorithms. A cross-validation experiment is provided to illustrate the robustness of our methods.

This paper presents experimental results related to the multi-moment non-linear filtering of chaotic signals. For simplicity of implementation only the particular case of two moments filtering (2MM) is developed here. The 2MM filtering approach is specially suited for estimation of extremely weak chaotic signals immersed on an accompanying noise signal (Additive White Gaussian Noise, AWGN) or together with some other type of information signal. The performance of the 2MM technique is rather efficient in the sense that very small values of the Normalized Mean Square Error (NMSE) can be achieved for Chaos/Noise or Chaos/signal ratios below 0 dB. This experimental study allows establishing clearly the trends of the multi-moment approach.
