We have designed a new self-adaptive image cropping algorithm that is able to detect several relevant regions in the image. These regions can then be sequentially proposed as thumbnails, to the user according to their relevance order, thus allowing the viewer to visualize the relevant image content and eventually to display or print only those regions in which he is more interested in. The algo...

In this paper, we deal with the task of determining the audio segment that best represents a given music recording (similar to audio thumbnailing). Typically, such a segment has many (approximate) repetitions covering large parts of the music recording. As main contribution, we introduce a novel fitness measure that assigns to each segment a fitness value that expresses how much and how well th...

This paper proposes a broadband asymmetrical monolithic microwave integrated circuit (MMIC) Doherty power amplifier (DPA) using 0.25-μm gallium-nitride process with compact chip size of 2.37 × 1.86 mm2 for 5G communication. It adopts an unequal Wilkinson’s divider ratio 2.5:1, where 71.5% the total is transferred to main higher gain. Different input matching networks are used offset phase diffe...

in this paper, we discuss the ways that communication accommodation theory (cat) can be a useful framework for understanding and diagnosing interactional issues in interpersonal and intergroup conflict situations. we argue that the theory’s construct of attuning strategies provides a multidimensional view of mutual adjustment, leading to insights relevant to successful versus unsuccessful confl...

We proposed an image signature method for content authentication, which applies a hierarchical approach to construct an image signature. In the first level, DWT and DCT are used to extract image features; then these features are encrypted by using sub-keys that are generated by a cryptographically hash function. In the second level, Karhunen–Loeve transformation is used to reduce the signature ...

The intent of this chapter is to provide the reader with a review of GeneChip technology and the complete system it represents, including its versatility, components, and the exciting applications that are enabled by this platform. The following aspects of the technology are reviewed: array design and manufacturing, target preparation, instrumentation, data analysis, and both current and future...

This paper presented a closed loop control of asymmetrical PWM full bridge converter; Renewable energy and distributed generation are getting more and more popular, wind turbines, and fuel cells. The renewable energy sources need the power electronics interface to the utility grid because of different characteristics between the sources and the grid. No matter what renewable energy source is ut...

Gait recognition can be regarded as a problem of uniquely representing spatiotemporal surfaces associated with a person’s walking pattern in an efficient manner. In this paper, we describe the approach of using projections of such surfaces onto subspace spanned by appropriate axes using a single framework. Two new algorithms for gait recognition are presented which use projection on subspace of...

This paper addresses the problem of recognition of emotional facial gestures from static images in thumbnail resolution. More experiments are presented, a holistic and two local approaches using SVM’s as classifier engines. The experimental results related to the application of our method are reported.
