Cypress Creek Flow Study: Blanco and Travis Counties, Texas

The Texas Hill Country is a unique place known for its stunning spring fed creeks, limestone bluffs, soaring cypress trees, and expansive scenic views. Over the past several years, the Meadows Center for Water and the Environment has been working to answer the question – How much water is in the Hill Country? Although this seems like a straightforward question that merits a straightforward answer, the reality is that the largely hidden and unknown complexities of Hill Country hydrogeology make it challenging to answer. Building upon the “How Much Water is in the Pedernales?” research, The Meadows Center teamed up with the Colorado River Land Trust to direct this question towards Cypress Creek, a significant tributary that joins the Pedernales River before it meets Lake Travis. The Cypress Creek watershed is currently made up of mostly ranchlands with steady spring flows and good water quality. Gaining a greater understanding of these types of natural systems and the interconnectedness between surface and groundwater allows for informed water planning, wise water policy and the health of Hill Country springs, streams, and rivers in the future.The Meadows Center for Water and the Environmen

Value of Lost Load: An efficient economic indicator for power supply security? A literature review

Security of electricity supply has become a fundamental requirement for well-functioning modern societies. Because of its central position in all sections of society, the present paper considers the economic consequences of a power supply interruption. The Value of Lost Load (VoLL) is a monetary indicator expressing the costs associated with an interruption of electricity supply. This paper reviews different methods for calculating VoLL, provides an overview of recently published studies, and presents suggestions to increase the explanatory power and international comparability of VoLL

A Cable Driven Parallel Robot with a Modular End Effector for the Installation of Curtain Wall Modules

The installation of curtain wall modules (CWMs) is a risky activity carried out in the heights and often under unfavorable weather conditions. CWMs are heavy prefabricated walls that are lifted normally with bindings and cranes. High stability is needed while positioning in order not to damage the fragile CWMs. Moreover, this activity requires high precision while positioning brackets, the modules, and for that reason, intensive survey and marking are necessary. In order to avoid such inconveniences, there were experiences to install façade modules in automatic mode using robotic devices. In the research project HEPHAESTUS, a novel system has been developed in order to install CWMs automatically. The system consists of two sub-systems: a cable driven parallel robot (CDPR) and a set of robotic tools named as Modular End Effector (MEE). The platform of the CDPR hosts the MEE. This MEE performs the necessary tasks of installing the curtain wall modules. There are two main tasks that the CDPR and MEE need to achieve: first is the fixation of the brackets onto the concrete slab, and second is the picking and placing of the CWMs onto the brackets. The first integration of the aforementioned system was carried out in a controlled environment that resembled a building structure. The results of this first test show that there are minor deviations when positioning the CDPR platform. In future steps, the deviations will be compensated by the tools of the MEE and the installation of the CWM will be carried out with the required accuracy automatically
