Cerebral palsy (CP) occurs in over 2 out of 1000 live births and can impair motor control and cognition. Our goal was to create a robotic rehabilitation environment that mimics real-life situations by allowing simultaneous exercise of upper and lower limbs. We chose to use the Lokomat as a gait robot and added a novel removable arm robot, called PASCAL (pediatric arm support robot for combined arm and leg training), that was integrated into the Lokomat environment. We also added a virtual reality (VR) environment that enables the subject to perform motivating game-like scenarios incorporating combined arm and leg movements. In this paper we summarize the design of PASCAL and present the novel virtual environment including first experimental results. The next step will be to test whether a combined application of the virtual environment and the two simultaneously working robots is feasible in healthy participants, and finally to clinically evaluate the entire system on children with CP.

We introduce a novel method for selecting and controlling smart appliances in physical spaces through a head-worn computing device with near-eye display and wireless communication. We augment a commercial wearable computing device, Google Glass, with a narrow-beam infrared emitter for this purpose. This configuration yields a usable beam width of 2 to 4 feet (60 to 120 cm) for targeting at room scale. We describe a disambiguation technique if infrared targeting hits multiple targets simultaneously. A target acquisition study with 14 participants shows that selection using head orientation with our device outperforms list selection on a wearable device. We also report qualitative data from using our device to control multiple appliances in a smart home scenario.

The building energy consumption simulation software DeST is used to analyze the effects of fixed shading over external window on energy consumption and efficiency, on the base of a residential building in Shanghai.The simulation results show that the fixed shading over south window has little effect on the overall energy saving of residential building.For east and west external window, if window area is not very large and its shading performance is better, the effect of fixed shading installation on energy saving is not obvious.On the contrary, if its area is large and its shading performance is ordinary, the effect is remarkable.Furthermore, when room ventilation capacity is poor, the effect of energy saving by fixed shading installation is more prominent.

Using combustion theory to research on the technical theoretical features of oxygen-enriched combustion technology application to the cement industry kiln.On the basis of this,engineering projects of that,a certain enterprise 3000 t/d cement clinker production line applied oxygen-enriched combustion technology,and its economic evaluation were calculated.The results showed that:applying Oxygen-enriched combustion technology to the existing cement clinker calcined equipments,the coal powder consumption,the volume of flue gas and CO2 concentration in the flue gas of unit cement clinker occurred regular changes,When the O2 concentration increased from 21％ to 30％,the coal powder consumption decreased by 17.78％,the flue gas volume was reduced by 12.73％ and the CO2 concentration in the flue gas increased to 76.57％.If the enterprise used the oxygen-enriched atmosphere of O2 concentration for 30％ to form the coal combustion,it can save coal about 71.87 t/d,equipment production capacity increase by 41.75％ and capture CO2 products about 2662 t.Every year,this resulted in the profit increasing 103 million yuan.

Minimization of energy consumption is one of the most important research areas in Wireless Sensor Networks.Nowadays,the paradigms of computational intelligence (CI) are widely used in WSN,such as localization,clustering,energy aware routing,task scheduling,security,etc.Though many fuzzy based clustering techniques have been proposed earlier,many of them could not increase the total network life time in terms of LND (Last Node Dies) with comparing to LEACH.In this paper,a fuzzy logic based energy-aware dynamic clustering technique is proposed,which increases the network lifetime in terms of LND.Here,two inputs are given in the fuzzy inference system and a node is selected as a cluster head according to the fuzzy cost (output).The main advantage of this protocol is that the optimum number of cluster is formed in every round,which is almost impossible in LEACH (low-energy adaptive clustering hierarchy).Moreover,this protocol has less computational load and complexity.The simulation result demonstrates that this approach performs better than LEACH in terms of energy saving as well as network lifetime.

The information generated from the Internet of Things (IoT) potentially enables a better understanding of the physical world for humans and supports creation of ambient intelligence for a wide range of applications in different domains. A semantics-enabled service layer is a promising approach to facilitate seamless access and management of the information from the large, distributed and heterogeneous sources. This paper presents the efforts of the IoT.est project towards developing a framework for service creation and testing in an IoT environment. The architecture design extends the existing IoT reference architecture and enables a test-driven, semantics-based management of the entire service lifecycle. The validation of the architecture is shown though a dynamic test case generation and execution scenario.
