Multiple color coordinate systems are usually involved in color image applications or systems. Forward and backward transformations are used to switch between color coordinate systems. The out of gamut problem emerges when the color coordinate systems’ gamut is different. Conventional approaches, including clipping R, G, B values and clipping luminance value are not ideal as they both produce s...

BACKGROUND AND PURPOSE The management of aneurysms is controversial because little is known about the impact of clipping on long-term outcome. This study was designed to evaluate long-term survival of patients with aneurysms undergoing clipping in a statewide population. METHODS We used a retrospective design using an administrative database to identify patients hospitalized with aneurysms (1...

Recent developments in broadband wireless technology heightened the need for WiMAX which assures high-speed data services. Mobile WiMAX is grounded on orthogonal frequency division multiplexing/orthogonal frequency division multiplexing Access (OFDM/OFDMA) technology which is an increasing important technique in LTE systems. This paper describes the OFDM transceiver implementation using softwar...

Internal carotid-posterior communicating artery (IC-PC) aneurysms account for more than 20% of all intracranial aneurysms. As a result of the increase in coiling, there has also been an increase in recurrent IC-PC aneurysms after coiling. We present our experience of 10 recurrent IC-PC aneurysms after coiling that were retreated using surgical or endovascular techniques in order to discuss the ...

A robust and an efficient source and channel coding algorithms is proposed in this paper for the purpose of progressive transmission of images over wireless communication systems. This paper presents a modified orthogonal frequency division multiplexing system for robust progressive image transmission. A joint source channel coder is employed in the modified OFDM system. The set Partioning hier...

Smart grid can be a solution for reducing greenhouse gas (GHG) emissions. To perform its task, smart grid needs a communication link to communicate between nodes or devices. Using power-line communications (PLC) is beneficial as the power-lines infrastructure has been available. However, in PLC the transmitted signal undergoes multipath channels and impulsive noise corruption. Meanwhile, orthog...

This study was carried out to establish clipping interval of Pennisetum orientale (PO) and Panicum antidotale (PA) to get maximum biomass production with optimal nutritional value for Nili buffaloes. Two clipping intervals i.e. CI1, and CI2 (clipped after every one and two months, respectively) were studied for both grasses. The data on various parameters were compared with PO and PA each clipp...

BACKGROUND AND PURPOSE The relative merits of treating ruptured aneurysms with clipping versus coiling continue to be a topic of debate. We evaluated a national, multihospital patient data base to examine recent trends in ruptured aneurysm therapies and to compare peri-procedural outcomes between clipping and coiling treatments. MATERIALS AND METHODS The Premier Perspective data base was used...
