Deep Learning (DL) techniques are now widespread and being integrated into many important systems. Their classification and recognition abilities ensure their relevance for multiple application domains. As machine-learning that relies on training instead of algorithm programming, they offer a high degree of productivity. But they can be vulnerable to attacks and the verification of their correctness is only just emerging as a scientific and engineering possibility. This paper is a major update of a previously-published survey, attempting to cover all recent publications in this area. It also covers an even more recent trend, namely the design of domain-specific languages for producing and training neural nets. Copyright © 2019, The Authors. All rights reserved.

Bluetooth is a radio technology for Wireless Personal Area Networking (WPAN) operating in the 2.4 GHz ISM frequency band, and allows devices to be connected into short-range ad hoc networks. The Bluetooth medium access control protocol is based on the Master/Slave paradigm wherein any communication between slave devices has to go through the Master. While this model provides for simplicity, it incurs a longer delay between any two slave devices due to far from optimal packet forwarding, the use of double the bandwidth, and also additional energy wastage at the Master. Moreover, if more than two devices want to communicate as a group, this can only be achieved by either multiple unicast transmissions or a piconet-wide broadcast, clearly resulting in inefficiency. In this paper, we propose a novel Dynamic Slot Assignment (DSA) scheme whereby the Master device dynamically assigns slots to Slaves so as to allow them to communicate directly with each other without any Master intervention. This proposed communication architecture also provides for Quality of Service (QoS) requests, admission control, and multi-device conversation by which a multicast-like communication is implemented within a piconet. Through extensive simulation, we observe that DSA drastically enhances Bluetooth performance in terms of delay and throughput, while significantly reducing power consumption at the master and the overall piconet. © 2004 Elsevier B.V.

distributed wisdom: Toward next-generation middleware

IEEE distributed Systems Online 2005年第3期6卷

作者： Kordon, Fabrice Pautet, Laurent Lab. d'Informatique de Paris 6 Télécom Paris Department of Computer Science Univ. Pierre et Marie Curie LIP6 Distributed and Coop. Syst. Dept. Netwk. and Comp. Sciences Department Télécom Paris

A large range of application domains, from real-time embedded systems to grid-comp.ting applications, requires distribution. A distribution model used is a set of mechanisms to handle distribution such as distributed object comp.ting, remote procedure call, and message passing. Middleware specifications such as Cobra or Java Message Service propose the API and protocols to support these models. Middleware aims to unify and ease the development of an application on top of a distribution model as general as possible.

2004 IEEE 15th International Symposium on Personal, Indoor and Mobile Radio Communications, PIMRC 2004

作者： Mukherjee, Anindo Gupta, Meetu Deng, Hongmei Agrawal, Dharma P. Ctr. Distributed Mobile Comp. Lab. University of Cincinnati Cincinnati OH 45221-0030

Many emerging mobile wireless applications use symmetric keys for secure multicast communication. This key has to be changed every time a user decides to leave or join the network. We introduce a novel hierarchical security framework for mobile Ad Hoc Multicast networks in which data encryption is done using a symmetric key and key establishment using symmetric 'level' keys and asymmetric node keys. Our primary contention is that the tree formation process should be integrated with the key exchange process and should not be treated as an add-on. Our scheme effectively handles the impact of mobility on key establishment while minimizing the number of messages to be exchanged.

Grids aim at exploiting synergies that result from cooperation of autonomous distributed entities. The synergies that result from grid cooperation include the sharing, exchange, selection, and aggregation of geographically distributed resources such as comp.ters, data bases, software, and scientific instruments for solving large-scale problems in science, engineering, and commerce. For this cooperation to be sustainable, participants need to have economic incentive. Therefore, "incentive" mechanisms should be considered as one of key design parameters of Grid architectures. In this article, we present an overview and status of an open source Grid toolkit, called Gridbus, whose architecture is fundamentally driven by the requirements of Grid economy. Gridbus technologies provide services for both comp.tational and data grids that power the emerging eScience and eBusiness applications.

Guided Google: A meta search engine and its implementation using the Google distributed Web services

International Journal of comp.ters and Applications 2004年第3期26卷 181-187页

作者： Ding, Choon Hoong Buyya, Rajkumar Grid Comp./Distributed Syst. Lab. Department of Computer Science University of Melbourne Australia

With the ubiquity of the Internet and Web, search engines have been sprouting like mushrooms after a rainfall. However, innovative search engines and guided search capabilities have started appearing only in recent years. For instance, Google, which is one of the popular search engines, supports Web services that allow external applications to issue Web search queries that are actually processed using Google's commodity cluster comp.ter made up of 15,000 PC nodes. The goals of these applications are to help ease and guide the searching efforts of novice Web users towards their desired objectives. A number of implementations of such services are emerging. This article proposes a guided meta-search engine called Guided Google that serves. as an advanced interface to the actual *** search engine.

Cluster comp.ters have become the vehicle of choice to build high performance comp.ting environments. To fully exploit the comp.ting power of these environments, one must utilize high performance network and protocol technologies, since the communication patterns of parallel applications running on clusters require low latency and high throughput, not achievable by using off-the-shell network technologies. We have developed a technology to build high performance network equipment, called Maestro2. This paper describes the novel techniques used by Maestro2 to extract maximum performance from the physical medium and studies the impact of software-level parameters. The results obtained clearly show that Maestro2 is a promising technology, presenting very good results both in terms of latency and throughput. The results also show the large impact of software overhead in the overall performance of the system and validate the need for optimized communication libraries for high performance comp.ting.
