Web-based malware equipped with stealthy cloaking and obfuscation techniques is becoming more sophisticated nowadays. In this paper, we propose J-FORCE, a crash-free forced JavaScript execution engine to systematically explore possible execution paths and reveal malicious behaviors in such malware. In particular, JFORCE records branch outcomes and mutates them for further explorations. J-FORCE ...

Pneumatic muscle is a new type of flexible actuator with advantages in terms of light weight, large output power/weight ratio, good security, low price and clean. In this paper, an ankle rehabilitation robot with two degrees of freedom driven by pneumatic muscle is studied. The force control method with an impedance controller in outer loop and a position inner loop is proposed. The demand of r...

Nowadays, hydraulic actuators play an important role in a modern industry where controlled force or position with high accuracy is the most significant demand. This paper presents a new kind of hydraulic load simulator (HLS) for conducting performance and stability test in the bench system where force control is important. The system model consists of a hybrid hydro-electric actuator and anothe...

The menisci have an essential function in force transmission across the knee. Injuries to the menisci are common. The indications for repair should be expanded, as the results of partial meniscectomy may deteriorate over time. Tears in younger, higher demand patients should be prepared to optimize the healing environment and be meticulously repaired, particularly in the setting of concurrent an...

Basic and applied research on microbial cellulases, hemicellulases and pectinases has not only generated significant scientific knowledge but has also revealed their enormous potential in biotechnology. At present, cellulases and related enzymes are used in food, brewery and wine, animal feed, textile and laundry, pulp and paper industries, as well as in agriculture and for research purposes. I...

Multiple access control is an important issue in Ethernet Passive Optical Networks (EPON). It is needed for traffic from different ONUs to share the upstream channel. The IEEE 802.3ah Ethernet in the First Mile (EFM) Task Force has specified a multipoint control protocol (MPCP) for this purpose. We propose a novel multiple access control scheme consisting of a parameter-based Call Admission Con...

A simple, low-cost and on-demand microfluidic controlling platform was developed based on a capillary-tuned solenoid microvalve suction effect without any outer pressure source. The suction effect was employed as a stable driving force for manipulating micro-fluid by connecting a piece of capillary tubing between the microvalve and the chip. The suction volume could be controlled from microlite...

We study dynamic monopoly pricing of storable goods in an environment where demand changes over time. The literature on durables has focused on incentives to delay purchases. Our analysis focuses on a different intertemporal demand incentive. The key force on the consumer side is advance purchases or stockpiling. In the case of storable goods the stockpiling motive has been documented in recent...

We investigated the mechanical function of two ankle extensor muscles, the lateral gastrocnemius (LG) and peroneus longus (PL), in wild turkeys Meleagris gallopavo during steady speed running. We hypothesized that mechanical work output of the LG and PL during running parallels the demand for mechanical work on the body. The turkeys ran on level, inclined (+6 degrees, +12 degrees ) and declined...

the increasing world demand for fish cannot be met by capture fisheries. aquaculture production is increasing and nowadays cage culture has an important role in meeting the world’s fish demand. the design of the physical structure of a cage is determined by the oceanographic conditions of the culture site. each design is site-specific and knowledge of the topography, wind force and direction, p...
