PURPOSE Robotic surgery is known to provide an improved technical ability as compared to laparoscopic surgery. We aimed to compare the efficiency of surgical skills by performing the same experimental tasks using both laparoscopic and robotic systems in an attempt to determine if a robotic system has an advantage over laparoscopic system. METHODS Twenty participants without any robotic experi...

PURPOSE To compare the performance of a computer-aided diagnosis (CAD) system for diagnosis of previously detected lesions, based on radiologist-extracted findings on masses and calcifications. MATERIALS AND METHODS A feed-forward, back-propagation artificial neural network (BP-ANN) was trained in a round-robin (leave-one-out) manner to predict biopsy outcome from mammographic findings (accor...

We focus on the recently introduced nearest neighbor based entropy estimator from Kraskov, Stögbauer and Grassberger (KSG) [10], the nearest neighbor search of which is performed by the so called box assisted algorithm [7]. We compare the performance of KSG with respect to three spatial indexing methods: box-assisted, k-D trie and projection method, on a problem of mutual information estimation...

In this paper, we propose and compare two video slicebased discard schemes, namely adaptive-PSD and Adaptive-ESD, for the transmission of MPEG video streams overATM best effort services. The schemes perform adaptive and selective cell burst discard at the level of MPEG video slices and intelligently adjusts drop policies to switch buffer occupancy and video cell payload types. In comparison to ...

We present the Preemptive Bandwidth Allocation Multicast Protocol; a distributed multicast QoS-aware signaling protocol that adapts the users’ bandwidth requirements to the limited resources available in the network by preempting bandwidth of less prioritized streams from existing multicast groups. We assume that each multicast group will have different multicast streams with predefined quality...

A new kind of plenoptic imaging system based on Laser Optical Feedback Imaging (LOFI) is presented and is compared to another previously existing device based on microlens array. Improved photometric performances, resolution and depth of field are obtained at the price of a slow point by point scanning. Main properties of plenoptic microscopes such as numerical refocusing on any curved surface ...

phenolic compounds, especially those of plant origin, constitute an essential part of the human diet, and are of considerable interest due to their antioxidant properties. in this study, ultrasound-assisted extraction (uae), microwave-assisted extraction (mae), as well as maceration extraction (me) methods were applied for phenolic compounds’ extraction from pistachio green hull. response surfa...

This paper describes the use of a new automatic evaluation technique to evaluate speech-enabled computer aided pronunciation learning (CAPL) systems. The CAPL system is a part of a computer aided automatic training of correct recitation for the holy Qur an for Arabic speakers. The proposed technique evaluates the system by measuring the degree of usefulness of its feedback to learners. Evaluati...
