Gas tungsten arc welding is fundamental in those industries where it is important to control the weld bead shape and its metallurgical characteristics. However, compared to the other arc welding process, the shallow penetration of the TIG welding restricts its ability to weld thick structures in a single pass (~ 2 mm for stainless steels), thus its productivity is relativity low. This is why th...

This paper analyzes stochastic performance of a distributed global activity, composed of sub-activities sequenced serially, probabilistically, or concurrently. We provide general formulas with which we calculate the performance of a composite activity based on the performance of the constituent sub-activities and the control structure. To do this, we model each sub-activity as a Partially Order...

Recently, we developed a formalism for the scattering from linear and acyclic branched structures build of mutually non-interacting sub-units. [C. Svaneborg and J. S. Pedersen, J. Chem. Phys. 136, 104105 (2012)] We assumed each sub-unit has reference points associated with it. These are well-defined positions where sub-units can be linked together. In the present paper, we generalize the formal...

The design and analysis of large and complex system requires frequently that the system is divided into smaller units, called sub-systems. The structure of overall system resulting from the interconnections of sub-systems can be very complex. One of the most common structures, is the hierarchical structure, i.e. the lay-out of the structure is vertical. Consequently in this report only hierarch...

This paper describes a VLSI architecture for classification of multiand hyperspectral imagery using Fuzzy Logic with trapezoidal membership functions. The fuzzy classifier is implemented using a rule-based approach, where each class is defined as a set of sub rules. There is only one sub rule associated to each band within a class. Each sub rule is implemented as a dedicated parallel hardware. ...

The goal of this project is to identify and localize objects in videos. Given a video V , consisting of a set of N frames f1, .., fN where each frame contains one or more unknown object, the objective is to identify and localize primary objects in each i-th frame fi in V that exhibit coherence in both appearance and motion. Figure 1 shows a brief illustration of discovering objects in videos pr...

In this paper, a Reliable Multicast transport protocol over combined (fixed/mobile) networks using Sub Sub-casting called (RMSS) is proposed. RMSS is based on a hierarchical structure where receivers are grouped into local regions. In each local region there are special receivers, which are called Designated Receivers (DRs) and Mobile Agents (MAs). Each DR or MA is responsible for retransmissio...
