Methodology for a dump design optimization in large-scale open pit minesPuell Ortiz, Jorge 05 October 2017 (has links)
Modern large-scale open pit mines move hundreds of thousands of tonnes of material daily, from the loading sources to the destination zones, whether these are massive mine dumps or, to a lesser extent, to the grinding mills. Mine dumps can be classified as leach or waste dumps, depending upon their economic viability to be processed in-place, a condition that has experienced great progress in the last decades and has reconfigured the open pit haulage network with an increase in the number of dumps. Therefore, new methods for dump design optimization are of the highest priority in mine planning management. This paper presents a methodology to model and optimize the design of a dump by minimizing the total haulage costs. The location and design of these dumps will be given mainly by the geological characteristics of the mineral, tonnage delivered, topographical conditions, infrastructure capital and transportation costs. Spatial and physical design possibilities, in addition, provide a set of parameters of mathematical and economic relationship that creates opportunities for modelling and thus facilitates the measurement and optimization of ultimate dump designs. The proposed methodology consists of: (1) Formulation of a dump model based on a system of equations relying on multiple relevant parameters; (2) Solves by minimizing the total cost using linear programming and determines a "preliminary" dump design; (3) Through a series of iterations, changes the "preliminary" footprint by projecting it to the topography and creates the ultimate dump design. Finally, an application for a waste rock dump illustrates this methodology.

The monetary sector in Cameroon money demand and causality analysisMbeleke, Paul Wuakoh January 1997 (has links)
This thesis investigates the monetary sector in Cameroon within an open economy framework. Two main hypotheses: money demand and Granger-causality are investigated. The data used are found to be non-stationary. Consequently, the money demand relationship is tested for the null hypothesis that it is spurious or not co-integrated. This is rejected in all the models put forward. The models are estimated and found to exhibit elasticities that are not unusual. Price homogeneity is found to be data incompatible. Income elasticities are generally found to be significantly less than unity suggesting economies of scale in money holdings. Corresponding dynamic models in the form of error correction are constructed using the familiar general to specific methodology and generally found to exhibit desirable statistical properties. Model preference is in terms of the narrow Ml definition of money with explanatory variables which include a foreign interest rate. For Granger-causality, the non-stationary data are transformed into stationarity where the null hypothesis of noncausality is tested in bivariate and multivariate contexts. Lag length selection is by the Final Prediction Error statistic. Results are mixed but two appear striking: domestic money and prices are found to be independent while domestic prices are Granger-caused by foreign variables but not by domestic ones.

Open City Data PipelineBischof, Stefan, Kämpgen, Benedikt, Harth, Andreas, Polleres, Axel, Schneider, Patrik 02 1900 (has links) (PDF)
Statistical data about cities, regions and at country level is collected for various purposes and from various institutions. Yet, while
access to high quality and recent such data is crucial both for decision makers as well as for the public, all to often such collections of
data remain isolated and not re-usable, let alone properly integrated. In this paper we present the Open City Data Pipeline, a focused
attempt to collect, integrate, and enrich statistical data collected at city level worldwide, and republish this data in a reusable manner
as Linked Data. The main feature of the Open City Data Pipeline are: (i) we integrate and cleanse data from several sources in a
modular and extensible, always up-to-date fashion; (ii) we use both Machine Learning techniques as well as ontological reasoning
over equational background knowledge to enrich the data by imputing missing values, (iii) we assess the estimated accuracy of such
imputations per indicator. Additionally, (iv) we make the integrated and enriched data available both in a we browser interface and as
machine-readable Linked Data, using standard vocabularies such as QB and PROV, and linking to e.g. DBpedia.
Lastly, in an exhaustive evaluation of our approach, we compare our enrichment and cleansing techniques to a preliminary version
of the Open City Data Pipeline presented at ISWC2015: firstly, we demonstrate that the combination of equational knowledge and
standard machine learning techniques significantly helps to improve the quality of our missing value imputations; secondly, we
arguable show that the more data we integrate, the more reliable our predictions become. Hence, over time, the Open City Data
Pipeline shall provide a sustainable effort to serve Linked Data about cities in increasing quality. / Series: Working Papers on Information Systems, Information Business and Operations

Diplomatie : reframing secrecy in the age of digital diplomacyLeray, Victor A. January 2015 (has links)
Magister Administrationis - MAdmin / The increasing importance of media, especially digital media in society has been studied widely, from identity formation to activist movements. In international relations, digital media studies have focused considerably on public digital diplomacy and social networks, sometimes neglecting a crucial step: the making, the processing and the transmission of the sacrosanct and secret diplomatic data. This study aims to explore how digital revolutions impact on the way diplomats
communicate and share information. The dependent question will revolve around the notion of secrecy; the independent question will analyse secrecy in the era of digital diplomacy. A statistical database was built and semi-structured interviews with American, French and South African diplomats have been conducted. It aims to highlight three thematic fields. The first one looks into organization, legitimacy, sovereignty and governance issues raised by the emergence of new technologies. The second one looks into the redefinition of secrecy in our digital era. The third part is a case study that will investigate how software, open platforms and processing of computerized data redefine, modernize and legitimize the way diplomats work, share information and engage with the general public for the greater good. The main assumption is that public action will only be legitimate in society if – and only if – society recognizes the state as a true network actor.

Inbound open innovation och innovationsprestation i små och medelstora företag : En kvantitativ analys av svensk fordonsindustriAndersson, Henrik January 2017 (has links)
Introduktion: Studien behandlar små och medelstora företag (SMFs) inom fordonsindustrin. Kontexten berörs med hänsyn till att forskningsfronten saknar empiriska exempel avseende relationen mellan olika inbound open innovation aktiviteter och företagens innovationsprestation. Fenomenet inbound open innovation innebär att företag genom olika samverkansaktiviteter utnyttjar externa flöden av kunskap och teknologi, för att främja framkomsten av nya produkter och processer. Följaktligen utreder studien relationen mellan företagens innovationsprestation och aktiviteterna; (1) teknologisk rekognosering, (2) vertikal teknologisk kollaboration, (3) horisontell teknologisk kollaboration, (4) teknologisk anskaffning. Syfte: Syftet med studien är att undersöka relationen mellan fyra former av inbound open innovation aktiviteter och innovationsprestation i små och medelstora företag, inom fordonsindustrin. Insikterna från studien ämnar stärka de små och medelstora företagens konkurrenskraft på en globaliserad marknad. Studien ämnar även främja helhetsbilden av vilken effekt olika inbound open innovation aktiviteter har i praktiken. Teori: Studien baseras på tidigare forskning och teorier avseende inbound open innovation i små och medelstora företag (SMFs). Metod: Studien bedrivs via en kvantitativ metodansats. Ett själv-administrerat frågeformulär har distribuerats ut via mail till 370 stycken VD:s. Insamlad data har bearbetats i SPSS genom flertalet statistiska tester, vilket utmynnade i att studiens fyra hypoteser testades och utreddes. Slutsats: Studiens resultat påvisar att SMFs inom fordonsindustrin kan förbättra sin innovationsprestation genom att bedriva aktiviteterna teknologisk rekognosering, vertikal teknologisk kollaboration samt horisontell teknologisk kollaboration. Aktiviteten teknologisk anskaffning befanns inte ha någon signifikant inverkan på innovationsprestationen. Studiens insikter kan stärka de små och medelstora företagens konkurrenskraft på en globaliserad marknad. Insikterna främjar även helhetsbilden avseende vilken effekt olika inbound open innovation aktiviteter har i praktiken. / Introduction: The study concerns small and medium-sized enterprises (SMEs) in the automotive industry. The context is touched because the research front lacks empirical examples of the relationship between different inbound open innovation activities and innovation performance. The phenomenon of inbound open innovation means that companies, through different collaborative activities, exploit external flows of knowledge and technology to promote the emergence of new products and processes. Consequently the study investigates the relationship between innovation performance and the activities; (1) technological scouting, (2) vertical technological collaboration, (3) horizontal technological collaboration, (4) technological acquisition. Purpose: The aim of the study is to investigate the relationship between four forms of inbound open innovation activities and innovation performance in small and medium-sized enterprises, in the automotive industry. The insights from the study aims to strengthen the competitiveness of SMEs in a globalized market. The study also aims to promote the overall picture of the impact of different inbound open innovation activities in practice. Theory: The study is based on previous research and theories regarding inbound open innovation in small and medium-sized enterprises (SMEs). Method: The study is conducted through a quantitative methodology. A self-administered questionnaire has been distributed by mail to 370 CEOs. The collected data has been processed in SPSS through different statistical tests, which resulted in the study's four hypotheses being tested and investigated. Conclusion: The studies result shows that SMEs in the automotive industry can improve their innovation performance by conducting the activities of technological scouting, vertical technological collaboration and horizontal technological collaboration. Technological acquisition was found to have no significant impact on innovation performance. The findings can promote the competitiveness of SMEs in a globalized market. The insights also promote the overall picture of the impact of different inbound open innovation activities in practice.

A Framework for using Open Source intelligence as a Digital Forensic Investigative toolRule, Samantha Elizabeth January 2015 (has links)
The proliferation of the Internet has amplified the use of social networking sites by creating a platform that encourages individuals to share information. As a result there is a wealth of information that is publically and easily accessible. This research explores whether open source intelligence (OSINT), which is freely available, could be used as a digital forensic investigative tool. A survey was created and sent to digital forensic investigators to establish whether they currently use OSINT when performing investigations. The survey results confirm that OSINT is being used by digital forensic investigators when performing investigations but there are currently no guidelines or frameworks available to support the use thereof. Additionally, the survey results showed a belief amongst those surveyed that evidence gleaned from OSINT sources is considered supplementary rather than evidentiary. The findings of this research led to the development of a framework that identifies and recommends key processes to follow when conducting OSINT investigations. The framework can assist digital forensic investigators to follow a structured and rigorous process, which may lead to the unanimous acceptance of information obtained via OSINT sources as evidentiary rather than supplementary in the near future.

Innovation adaptation and institutionalization: a case study of an open and distance learning adaptation in ZimbabweMswazie, Jonathan L P January 2014 (has links)
This study set out to investigate a unique case of innovation adaptation and institutionalization in a depressed socio-economic environment. The main aim of the study was to understand and explain interventions and innovative strategies that underpin the survival and growth of the Open and Distance Learning Mode (ODLM) in Zimbabwe. Towards this end, the data to address the research questions was derived from the case study methodology which incorporated, among others, documentary analysis and interviews with persons involved in the initiation and management of the ODLM. The results of the study indicate that three broad categories of strategies, namely protectionism, innovative leadership and educational entrepreneurialism or commodification constitute the foundation of ODLM durability in Masvingo Province. Protectionism in the context of ODLM survival and growth are projected and articulated in the policy instruments such as mandates and legal frameworks which shielded the innovation from the usual hazards of the innovation process. Protectionism enabled the ODLM to gain traction in an elitist and conservative higher education landscape. Correspondingly, innovative leadership is manifested in a highly motivated team of management staff committed to the propagation of the ODLM to every part of Masvingo Province. The leadership at the Masvingo Regional Campus (MRC) utilizes the multiple stakeholder approach as strategy for establishing convergences and equilibrium in respect of the interests and concerns of the four main stakeholders, namely the government or the ruling party which initiated the implementation of the ODLM; the employers of ODL graduates who affirm the relevancy of ODL qualifications, the students who sustain ODLM by generating revenue for the ZOU, and finally, the MRC staff who are the implementers of the ODLM programmes. Likewise, educational entrepreneurialism constitute another key strategy in ODLM survival and growth. This strategy is articulated in the principle of continual adaptation and creation of market – driven programmes. The above results have several implications to various role players and actors involved in the educational reform and innovation. Firstly, the results of the study reveal the imperative for power elites or policy formulators to ensure that they initiate and adopt educational innovations that match the capacities of their implementers and the socio-economic realities of their respective countries or societies. In this regard, the ODLM appears to have been a prudent choice in light of the challenges that were being encountered in post-independence Zimbabwe. Secondly, from a management perspective, the selection of the innovation team to spearhead or steer the implementation was prioritized. Only competent and committed personnel positively disposed towards an innovation should spearhead the implementation. In addition adequate training and staff development should be instituted to keep the implementers abreast of new trends and standards in educational provision. Lastly, the results of this study constitute a clarion call to curriculum developers in African university departments to design and develop programmes which resonate with the needs of key stakeholders who constitute the support base for viable educational institutions.

Open Platform Semi-Passive Ultra High Frenquency Radio Frequency IdentiLi, Tzu Hao January 2011 (has links)
Radio frequency identi cation (RFID) is a rapidly emerging technology that enables au-
tomatic remote identi cation of objects. Passive and semi-passive RFID systems can be
distinguished from other forms of wireless systems, because the RFID tags (transponders)
communicate by way of backscatter. In addition, passive tags derive their energy from
the RF energy emitted by the reader. RFID technology can provide a fully automated
data capture and analysis system.
Compared to a passive RFID system, an open platform semi-passive UHF RFID
tag can provide identi cation, security, low-power (compared to a wireless sensor net-
work(WSN)), medium range and medium processing speed. However, the eld of semi-
passive RFID is still under development, and has yet there are no open development
platforms available.
This thesis develops a prototype of a semi-passive UHF RFID tag that is compatible
with the leading UHF RFID standard EPCglobal Gen 2 Class 1. I alsot has the
exible
I2C and analog digital converter(ADC) interface, which allows the additional of external
analog and digital sensors. The sensor data can be read by microcontroller and stored at
memory. Standard reader can get sensor data by sending QUERY and READ command
to tag.
Test results of our open platform semi-passive UHF RFID tag demonstrated that it
can achieve a read rate above 50% when an open platform semi-passive UHF RFID tag
is placed four meters from the reader antenna and the reader output power is set to 21
dBm. In addition, the proposed semi-passive open platform RFID tag consumes very
little power (4.9 mA in 2V with system frequency set to 8MHz).
