In this paper, a novel contrast enhancement technique for contrast enhancement of a low-contrast satellite image has been proposed based on the singular value decomposition (SVD) and discrete cosine transform (DCT). The singular value matrix represents the intensity information of the given image and any change on the singular values change the intensity of the input image. The proposed techniq...

A recent field of investigation concerns the efficiency of flapping flyers, the major interrogation being about how natural systems optimize energy saving together with performance enhancement. In particular, the passive role of wing flexibility to increase flight efficiency through the bending of the wings while flapping has attracted a lot of attention. It is commonly agreed that this efficie...

Signal-to-noise ratio (SNR) scalability has been incorporated into the MPEG-2 video-coding standard to allow for the delivery of two services with the same spatial and temporal resolution but different levels of quality. Scalable video coding has many advantages, such as its capability of coping with bandwidth variations, high flexibility and so on. However, few accurate rate control schemes fo...

Objective Chronic Non-specific low back pain (CNSLBP) is described as pain whose pathoanatomical cause cannot be determined. The current study aimed to evaluate the impact of retro-walking on pain, flexibility, and physical functions in patients with CNSLBP. Methods: A randomized controlled trial was conducted in Physical Therapy department of District Head Quarter hospital Nankana Sahib, Punj...

We demonstrate a real-time, open source implementation of the online GCC-NMF stereo speech enhancement algorithm. While the system runs on a variety of operating systems and hardware platforms, we highlight its potential for real-world mobile use by presenting it on two embedded systems: the Raspberry Pi 3 and the NVIDIA Jetson TX1. The effect of various algorithm parameters on subjective enhan...

A fi rewall is a collection of components interposed between two networks that fi lter traffi c between them according to some security policy [1]. Typically, fi rewalls rely on restrictions in the network topology to perform this fi ltering. One key assumption under this model is that everyone on the protected network(s) is trusted, since internal traffi c is not seen by the fi rewall and thus...

By blending storytelling with topics in biology, a fun activity can be created for students to strengthen their scientific knowledge (1-3). The “Sci-Fi Microbe” writing assignment lets students create an altered version of a known microorganism, and write a story describing an unusual observation that leads the characters discovery of their new microorganism. The Sci-Fi Microbe exercise is appr...
