While Large Language Models (LLMs) have shown impressive capabilities in math problem-solving tasks, their robustness to noisy inputs is not well-studied. In this work, we propose ArithmAttack examine how robust the LLMs are when they encounter prompts that contain extra noise form of punctuation marks. being easy implement, does cause any information loss since words added or deleted from context. We evaluate seven LLMs, including LLama3, Mistral, and Mathstral, on GSM8K MultiArith...

In semi-arid regions, reduced river flows present is a major challenge in water resources management. We new standardized contribution of rainfall to runoff index (SCRI) for evaluating changes flow. employ the precipitation (SPI), discharge (SDI) and SCRI characterize meteorological drought, hydrological drought land-use change impacts on flow, respectively. These indices are applied Mond River Basin (Iran), which regulated by Salman Farsi Tangab dams since 2006. A concept called "mirage...

Abstract This paper proposes an approach to estimate groundwater recharge using optimization‐based water‐table fluctuation method combined with a balance model in arid hardrock‐alluvium region, located at the Oman–United Arab Emirates border. We introduce “effective hardrock thickness” term identify percentage of considered thickness which effective flow takes place. The proposed is based upon Thiessen polygon zoning approach. includes subpolygons represent specific geologic units and...

Groundwater over-abstraction and the resulting decline in groundwater level quality have limited agricultural activities many parts of world. The desire for maximizing short-term benefits fear free riding by other uses discourage farmers from reducing current water levels. This results a classis tragedy commons which beneficiaries will experience long-term profit losses due to their unsustainable use groundwater. paper develops mathematical modeling framework understanding value cooperation...

Population growth and socio-economic development make the competition for larger share in water allocation more intense among stakeholders watershed, which turn brings up conflicts over use of water.Competition shares between stakeholders, especially dry areas, leads to over-exploitation resources large deficits supplying downstream demands.Equitable reduces since it provides equal opportunity usage them.Equitable sharing upstream is a promising approach equitable allocation.Karkheh...

This work describes a new mathematical model to predict the so-called aircraft handling qualities via proper positioning of mass in early stages design process. The methodology aims help make and therefore pilot rating an integral part main idea is find distributions for given flight conditions based on well-known quantitative measures flying described military standards. proposed allows designers associate density different segments have prior insight about optimum arrangement internal...

For a flexible power system, FACTS systems that are based on controllable electronic have been developed. In this paper relevant facts device which is used for voltage stability improvement, allocation problem has studied. The target FACTs in study SVC. Line index should be lower than 1 as Stability Index (SI). Also n-2 contingency criteria met, hence location of SVC with SI under normal and modeled. To solve problem, direct search algorithm way all possible tested at contingencies best...
