The remote control not only implements a full range of video conferencing control functions with an easy-to-use visual interface;but also implement cross-platform feature to allow users to use remote control software on their own equipment. It is economic, convenient and stylish for users. This paper mainly describes the design and implementation of remote control system framework and cross-platform features. Finally, the result in the paper shows: This remote control is reliable and easy to use.展开更多

For example, the mobile applications usually require frequent cross-equipment compatibility. This paper proposes a reasonable BIM-based FM cross-platform framework and develops a mobile application on the basis of an existing BIM-based FM system. The developed mobile application is applied in a case study of a metro station project in Guangzhou to verify its effectiveness in FM practice. It helps maintenance staff in viewing BIMs, accessing related information, and updating maintenance records in a unique platform. The test results demonstrate that the proposed BIM-based cross-platform framework meet the FM application requirements and supports the extension of FM functions.展开更多

The various available platforms make cross-study validations/comparisons difficult. Meanwhile, sample sizes of the studies are fast increasing, which poses a heavy computational burden to even the fastest PC.Here, we describe a novel method that can generate a platform-independent dataset given SNP arrays from multiple platforms. It extracts the common probesets from individual platforms, and performs cross-platform normalizations and summari-zations based on these probesets. Since different platforms may have different numbers of probes per probeset (PPP), the above steps produce preprocessed signals with different noise levels for the platforms. To handle this problem, we adopt a platform-dependent smoothing strategy, and produce a preprocessed dataset that demonstrates uniform noise levels for individual samples.To increase the scalability of the method to a large number of samples, we devised an algorithm that split the samples into multiple tasks, and probesets into multiple segments before submitting to a parallel computing facility. This scheme results in a drastically reduced computation time and increased ability to process ultra-large sample sizes and arrays.展开更多

U...With so many potentially interconnected electronic devices in today’s homes, manufacturers have to think of theirs as only one of the components involved in a general user experience, and not as an isolated device. Users are likely to be using several devices at the same time, either actively through immediate interaction, or passively by expecting devices to give them notifications when necessary, for example. Thus, having cross-devices functionalities is often necessary for a product to be really adapted to its usage situation. Moreover, just as we install software on computers, smartphones and tablets for additional functionalities to use their own hardware, it would be logical to install cross-devices software to use the combined hardware of several home devices for a better user experience. However, even though a number of technologies can be used to transmit data or commands between devices, UPnP being a widespread example, it is not possible to access the behavior of remote devices and add functionalities to them this way. Thus, when manufacturers design their products, there is no way for them to make full use of the other appliances at the user’s home without developing and deploying specific software on each of them. In order to address this issue, this paper discusses a platform for generic development and on-the-fly deployment of applications on home devices. This system aims at letting device vendors deploy innovative features across devices in a home network, without requiring prior knowledge or control over devices already present in the user’s environment. For this platform to be fit for consumer devices, it is designed to be cost-effective, use recent and widespread technologies, and be fast to implement and work with.展开更多
