Improvement in Social Competence Using a Randomized Trial of a Theatre Intervention for Children with Autism Spectrum Disorder.

Ian Muse, Blythe Corbett, A. Key, L. Qualls, S. Fecteau, C. Newsom & P. Yoder
The efficacy of a peer-mediated, theatre-based intervention on social competence in participants with autism spectrum disorder (ASD) was tested. Thirty 8-to-14 year-olds with ASD were randomly assigned to the treatment (n = 17) or a wait-list control (n = 13) group. Immediately after treatment, group effects were seen on social ability, (d = .77), communication symptoms (d = -.86), group play with toys in the company of peers (d = .77), immediate memory of faces...

Modeling Responses of Naturally Fractured Geothermal Reservoir to Low-Pressure Stimulation

Pengcheng Fu & Charles R. Carrigan
Hydraulic shearing is an appealing reservoir stimulation strategy for Enhanced Geothermal Systems. It is believed that hydro-shearing is likely to simulate a fracture network that covers a relatively large volume of the reservoir whereas hydro-fracturing tends to create a small number of fractures. In this paper, we examine the geomechanical and hydraulic behaviors of natural fracture systems subjected to hydro-shearing stimulation and develop a coupled numerical model within the framework of discrete fracture network modeling....

Investigation of Stimulation-Response Relationships for Complex Fracture Systems in Enhanced Geothermal Reservoirs

Pengcheng Fu, Scott M. Johnson & Charles R. Carrigan
Hydraulic fracturing is currently the primary method for stimulating low-permeability geothermal reservoirs and creating Enhanced (or Engineered) Geothermal Systems (EGS) with improved permeability and heat production efficiency. Complex natural fracture systems usually exist in the formations to be stimulated and it is therefore critical to understand the interactions between existing fractures and newly created fractures before optimal stimulation strategies can be developed. Our study aims to improve the understanding of EGS stimulation-response relationships by developing...

Using Fully Coupled Hydro-Geomechanical Numerical Test Bed to Study Reservoir Stimulation with Low Hydraulic Pressure

Pengcheng Fu, Scott M. Johnson & Charles R. Carrigan
This paper documents our effort to use a fully coupled hydro-geomechanical numerical test bed to study using low hydraulic pressure to stimulate geothermal reservoirs with existing fracture network. In this low pressure stimulation strategy, fluid pressure is lower than the minimum in situ compressive stress, so the fractures are not completely open but permeability improvement can be achieved through shear dilation. We found that in this low pressure regime, the coupling between the fluid phase...

University Of Southern California-Information Sciences Institute
The dataset contains background traffic and a malware DDoS attack traffic that utilizes a number of compromised local hosts (within 172.28.0.0/16 network). These hosts were used to launch a malware DDoS attack on a non local target. The victim with the IP address 152.162.178.254 was targeted on the TCP destination port 499.

University Of Southern California-Information Sciences Institute
Traffic contains a SYN flood DDoS attack on one target (IP address 172.28.4.7) and background traffic. The DDoS traffic comes from about 100 different IPs. Some IPs contribute significantly to the attack (e.g., IPs: 19.202.221.71, 19.202.221.72, and 19.202.221.73), while the contribution of some other sources is stealthier.

Newberry Well 55-29 Stimulation Data

Trenton Cladouhos
The Newberry Volcano EGS Demonstration in central Oregon, a 3 year project started in 2010, tests recent technological advances designed to reduce the cost of power generated by EGS in a hot, dry well (NWG 55-29) drilled in 2008. First, the stimulation pumps used were designed to run for weeks and deliver large volumes of water at moderate well-head pressure. Second, to stimulate multiple zones, AltaRock developed thermo-degradable zonal isolation materials (TZIMs) to seal off...
