Decision Taking is discussed in the context of the role it may play for a selling agent in a search market, in particular for agents involved in the sale of valuable and relatively unique items, such as a dwelling, a second hand car, or a second hand recreational vessel. Detailed connections are made between the architecture of decision making processes and a sample of software technology based...

We studied the notion of human verification of software-based attestation, which we base on the Pioneer framework. We demonstrate that the current state of the art in software-based attestation is not sufficiently robust to provide humanly verifiable voting machine integrity in practice. We design and implement a selfattesting machine based on Pioneer and modify, and in some cases, correct the ...

A basic question of instructional interventions is how effective it is in promoting student learning. This paper presents a study to determine the relative efficacy of different instructional strategies by applying an educational data mining technique, learning decomposition. We use logistic regression to determine how much learning is caused by different methods of teaching the same skill, rel...

The evaluation of the role different agronomic strategies in achieving sustainable wheat yields under variable Mediterranean climate conditions may involve use resource-use indicators that combine productivity and environmental impact. A two-seasons field experiment was conducted South Portugal to study effect water regimes nitrogen fertilization on yield, grain quality evaluated with footprint...

In this paper we present a new class of side-channel attacks on computer hard drives. Hard drives contain one or more spinning disks made of a magnetic material. In addition, they contain different magnets which rapidly move the head to a target position on the disk to perform a write or a read. The magnetic fields from the disk’s material and head are weak and well shielded. However, we show t...

Workstations typically depend on remote servers accessed over a network for such services as mail, printing, storing files, booting, and time. The availability of these remote services has a major impact on the usability of the workstation. Availability can be increased by replicating the servers. In the Echo distributed file system at DEC SRC, two different replication techniques are employed,...

As recent adversaries turned their eyes to attacking a system through non-control kernel data, in order to ensure the integrity of the kernel, the need arose for verifying noncontrol kernel data. This complicates typical security measures relying on integrity specifications set by security administrators, as it is non-trivial to manually encompass specifications for noncontrol kernel data. Fore...

The deployment of HEP applications in heterogeneous grid environments can be challenging because many of the applications are dependent on specific OS versions and have a large number of complex software dependencies. Virtual machine monitors such as Xen could be used to package HEP applications, complete with their execution environments, to run on resources that do not meet their operating sy...

The carbohydrate contents of sweet sorghum (Sorghum bicolor L. Moench) is an important industrial factor for crystal sugar or bioethanol production. In this study the relationship between growth analysis and carbohydrate contents were studied to recognize the best growth stages for sweet sorghum harvesting. Five sweet sorghum cultivars and four sweet sorghum lines were evaluated for leaf area i...
