For a multi-sensor target tracking system in a cluttered environment, the effects of temporally staggered sensors on system performance are investigated and compared with those of synchronous sensors. A probabilistic data association filter (PDAF) is used to track the target. Measurements from local sensors are fused in a centralized manner for the system with synchronous sensors. The system pe...

In this paper, a novel approach based on the Thévenin tracing is presented to modified conventional impedance-based out-of-step (OOS) protection. In conventional approach, the OOS detection is done by measuring positive sequence impedance. However, the measured impedance may be change due to different factors such as capacitor bank switching and reactive power compensators that it can cause the...

OBJECTIVES Patients with advanced stage colorectal carcinoma (CRC) display hepatic metastases on initial staging in up to 20% of cases. The effectiveness of chemotherapy is generally evaluated by computed tomography (CT) imaging using standardized criteria (RECIST). However, RECIST is not always optimal, and other criteria have been shown to correlate with pathologic response and overall surviv...

State estimation in the energy management center of active distribution networks has attracted many attentions. Considering an increase in complexity and real-time management of active distribution networks and knowing the network information at each time instant are necessary. This article presents a two-step multi-area state estimation method in balanced active distribution networks. The prop...

A pilot experiment was conducted by NSUOC and DLR in April-June 2008 in the Straits of Florida near Port Everglades, Florida in order to study the dynamics of far wakes of ships. In this experiment, a small boat with downward-looking sonar made “snake-like” sections through wakes of ships of opportunity during the TerraSAR-X overpasses. The ship identity and its parameters (length, speed, cours...

Hilsa shad (Tenualosa ilisha) is an anadromous species which has reproductive migration from the Persian Gulf to the river. Morphological properties and histological changes in oocyte of Hilsa shad in two different environments (salt water and fresh water in Khuzestan province) were studied with respect to its reproductive cycle. Twenty fish samples with average weight of 830.75±3.25 ...

synchronous cancer is referred to two or more histological distinct malignancies diagnosed during the same hospital admission. globally more than 1 million people get colorectal cancer yearly resulting in about 0.5 million deaths. vulvar cancer is the fourth most common gynecologic cancer (following the corpus uterine cancer, cancer of ovary and cervix) and comprises only 4 percent of malignanc...
