MULTI-LEVEL SECURE DATA DISSEMINATIONPanossian, Garo 01 June 2019 (has links)
Multi-level security is prevalent within the military; however, the private sector has not yet invested in the approach. As big data, Internet of things, and artificial intelligence drive businesses to collaborate (share data, algorithms, and tools) the need to secure such resources while simultaneously sharing them will push towards an alternative approach-–namely Multi-level security. The military labels data according to the sensitivity it carries as related to national security. Furthermore, the military restricts access by both the overall trust in the individual and by their need-to-know. To put it another way, data has a certain level of sensitivity and only those individuals that can be trusted with the data and have a need-to-know shall have access to such data. Military organizations not only limit access to digital data but also to sensitive discussions, often having sensitive talks within a Sensitive Compartmented Information Facility referred to as a SCIF. Irrespective of the media, all data must be secured and disseminated in order to produce value. Inaccessible data has no real value, as data must be accessible in order to be actionable and produce value. Along the same lines, data often requires aggregation to become actionable.
Creating a security domain with multiple levels of trust and need-to-know ensures that data can both be accessed and aggregated. Multi-level secure domains exist in military organizations today, however, the challenge arises when two domains want to share data—hence the need for multi-level secure data dissemination. One way to accomplish this objective is for Domain X to contact Domain Y and together identify how their two security domains can map to one another. After determining the mapping Domain X can send Domain Y data, however, what if Domain Z wants access to the same data? Should Domain Z request the data from Domain Y? Would Domain Y violate the trust of Domain X, if Domain Y disseminates the data? Perhaps, Domain Z is only cleared to a portion of the data. These are the issues related to the dissemination of MLS data within a multi-domain environment.
The objective of this project is to propose a solution that would allow domains to securely disseminate data without the need to repackage the data for each domain. The solution outlined in this project, leverages Simple Public Key certificates, Active Bundle, and a directory server. When combined, the three technologies allow domains: to convey both trust and authorization policies, learn about trust and authorization policies of external domains, and provide a mechanism to securely disseminate data.

The Efficacy of Massed Versus Distributed Practice As a Function of Desired Learning Outcomes and Grade Level of the StudentMoss, Vanessa D. 01 May 1995 (has links)
The study examined the extent to which type-of-practice strategies (massed or distributed) had an effect on learning a verbal information (reading) or intellectual skill (math) task for second- and fourth-grade students. One hundred and ninety students from eight second- and fourth-grade classrooms participated in the study. Classrooms were randomly assigned to the two practice conditions and all students participated in a 9- week integrated learning system (ILS) intervention.
The present study found that intellectual skill tasks are learned slightly more effectively in a massed than distributed practice mode, though the difference was not statistically significant. Students also learned verbal information tasks more effectively in the massed practice mode, though the difference was not statistically significant. The differences between the two practice conditions were not as great on verbal information tasks, however, and no statistically significant differences were found. Additional analyses, using the number of lesson units completed, showed that having completed a greater number of math lessons had a positive effect on the math test scores. These analyses suggest that a stronger treatment or better adherence to the treatment could have caused a statistically significant effect for massed practice in intellectual skill domains. Replication is needed to provide a more solid foundation for this assertion.
It was concluded from this study, due to the moderate effect size differences and the identical cost factor for incorporating the two types of practice, that the use of massed practice would be more prudent for intellectual skill tasks. Massed practice is also more effective in the higher order verbal information area. Strong research inference suggests the continuance of distributed practice for "lower level" tasks, particularly in the verbal information areas. Further research is needed to discover factors that limit or negate the spacing effect.

Paleogeography and sedimentology of the MacKenzie Basin, Northwest Territories, Canada: An evaluation of Devonian sea-level change, paleoecological controls on Paleozoic reef growth, and early diagenetic conditions.Corlett, Hilary 11 1900 (has links)
The MacKenzie Basin, located in the District of MacKenzie in the
southern part of the Northwest Territories, Canada, includes a thick succession of Middle Devonian strata. This basin, bordered to the east by the Canadian Shield and to the south by the Tathlina Uplift, was directly connected to the open ocean that lay to the northwest. Comprehensive facies analyses of the Chinchaga Formation, Lonely Bay Formation, Horn Plateau Formation, and Horn River Formation, which formed in this basin during the Early and Middle Devonian, shows that sedimentation was largely controlled by eustatic sea level changes. Accordingly, these strata reflect a long period of sea level rise during which shallow water evaporite deposition in the Eifelian was followed by open marine conditions that led to reef growth in the Givetian, and ultimately pelagic shale deposition in the Frasnian.
The Horn Plateau Formation is comprised of numerous isolated reefs
that are located along northeast-southwest direction over a distance of 350 km along the MacKenzie Basin ramp. Reefs in the southwest are dominated by
stromatoporoids whereas those in the northeast are dominated by corals. Although difficult to prove, it appears that the distribution of the stromatoporoids and corals may have been controlled by nutrients coming from coastal upwelling or runoff from the exposed Canadian Shield.
Effects of early diagenetic processes were evident on the MacKenzie
Basin ramp in an intensely bioturbated facies in the Lonely Bay Formation.
Burrows from this facies are dolomite-filled further down the ramp and calcite-filled proximal to the Canadian Shield in the east. Anoxic conditions and the
presence of sulphate reducing bacteria may have promoted early dolomite
formation in the burrows located in deeper water. Burrows further up the ramp were oxygenated and show evidence of input from the exposed Canadian Shield, both of which may have inhibited low-temperature dolomite formation.

Transportation system modeling using the High Level ArchitectureMelouk, Sharif 30 September 2004 (has links)
This dissertation investigates the High Level Architecture (HLA) as a possible distributed simulation framework for transportation systems. The HLA is an object-oriented approach to distributed simulations developed by the Department of Defense (DoD) to handle the issues of reuse and interoperability of simulations. The research objectives are as follows: (1) determine the feasibility of making existing traffic management simulation environments HLA compliant; (2) evaluate the usability of existing HLA support software in the transportation arena; (3) determine the usability of methods developed by the military to test for HLA compliance on traffic simulation models; and (4) examine the possibility of using the HLA to create Internet-based virtual environments for transportation research. These objectives were achieved in part via the development of a distributed simulation environment using the HLA. Two independent traffic simulation models (federates) comprised the environment (federation). A CORSIM federate models a freeway feeder road with an on-ramp while an Arena federate models a tollbooth exchange.

Programming of Microcontroller and/or FPGA for Wafer-Level Applications - Display Control, Simple Stereo Processing, Simple Image RecognitionPakalapati, Himani Raj January 2013 (has links)
In this work the usage of a WLC (Wafer Level Camera) for ensuring road safety has been presented. A prototype of a WLC along with the Aptina MT9M114 stereoboard has been used for this project. The basic idea is to observe the movements of the driver. By doing so an understanding of whether the driver is concentrating on the road can be achieved. For this project the display of the required scene is captured with a wafer-level camera pair. Using the image pairs stereo processing is performed to obtain the real depth of the objects in the scene. Image recognition is used to separate the object from the background. This ultimately leads to just concentrating on the object which in the present context is the driver.

An insight to Level Communication through the use of Cameras : a Project ReportLewis, Jonas January 2013 (has links)
The following paper is a documentation and project report of the construction of a project called Synergy. It details the underlying notion, investigation, procedure, and learning that lead to the construction, as well as the reflection upon a level design. Which purpose was to impose a heightened level of authorial control to its creator; thereby more fluidly conveying a creator's ambitions to its audience through the use of cinematographic cues. Upon the project's completion further investigations was done in respect to the finished product whereby I found that others had constructed similar systems, though not for the same cause.

The Institutional Reform of Land Development of Mainland China¡GA case study on urban regeneration in Putian CityLee, Yu-pin 29 August 2005 (has links)
The Institutional Reform of Land Development of Mainland China¡G
A case study on urban regeneration of Putian City.
The Peoples' Republic of China launched economic reforms and open-door policy in 1978.After that, China launched the compensatory transfer of land ownership system in which land could be sold in terms of money. China's real estate industry had kept a rapid growth momentum; Chinese government has taken real estates industry as a new drive for its economic growth. On the policy background of decentralization of powers among government level, the district governments owned strong financial autonomy and land approval rights, thus promoting district rent seeking behavior have become the key factors which attracted the district government to release land into the real estate market positively.
After economic reform in China, central government relegated more authority to subordinate level of governments, make place bureaucrat enjoy power of measuring and decision, because the land development system is complicated and has local personalities again on the other hand, so this study proceeds from the investigation view of Taiwan trader invested in, with Putian City of Fujian Province, Field case was used to verify the Current Situation and Difficulties that Taiwan trader is facing while investigating real estate in the specific city of Mainland China, to supplement the investigation result which had been done by Jin¡¦s (2001) in land development system.
The main conclusion of this study is as follows¡G
1. The comprehensive network relationship with relevant government department, and organizational operation, planning strategy and management performance is very important to land development project.
2. Expropriation compensation and the settle down procedure is more and more Institutionalize gradually.
3. The government manages efficiency low, and postpone redevelopment schedule painstakingly in high perplexity renewal area.
4. The coastal second level city, like Putian City, is indeed suitable for medium-size enterprise of Taiwan to develop real estate career.
