CREASE: Certificateless and REused-pseudonym based Authentication Scheme for Enabling security and privacy in VANETs
CREASE: طرح احراز هویت مبتنی بر نام مستعار بدون گواهی و استفاده مجدد برای فعال کردن امنیت و حریم خصوصی در VANET-2022 Due to the customers’ growing interest in using various intelligent and connected devices, we
are surrounded by the Internet of Things (IoT). It is estimated that the number of IoT devices
will exceed 60 billion by 2025. One of the primary reasons for such rapid growth is the Internet
of Vehicles (IoV). Internet of Vehicles (IoV) has evolved into an emerging concept in intelligent
transportation systems (ITS) that integrates VANETs and the IoT to enhance their capabilities.
With the emergence of IoV and the interest shown by customers, Vehicular Ad hoc NETworks
(VANETs) are likely to be widely deployed in the near future. However, for this to happen, wide
participation of vehicle owners in VANET is needed. The primary concerns of vehicle owners
to participate in VANET are privacy and security. In this paper, we present a Certificateless and
REused-pseudonym based Authentication Scheme for Enabling security and privacy (CREASE) in
VANETs. One of the ways to preserve the privacy of vehicles/drivers is to allow vehicles/drivers
to use pseudo identities (pseudonyms) instead of their real identities (such as VIN number or
driving license number) in all communications. The pseudonym used by a vehicle needs to
be changed frequently to prevent the vehicle from being tracked. Our scheme uses Merkle
Hash Tree and Modified Merkle Patricia Trie to efficiently store and manage the pseudonyms
assigned to a vehicle. This enables a vehicle to pick and use a random pseudonym from a
given set of pseudonyms assigned to it as well as change its pseudonym frequently and securely
to ensure privacy. Unlike many of the existing schemes, our scheme does not use certificates
and certificate revocation lists for authentication. Moreover, it allows vehicles to get a set of
pseudonyms only once from the trusted authority. We present a formal proof of correctness of
our scheme and also compare our scheme with some of the other contemporary schemes to
show the effectiveness of our scheme.

A Software Development Kit and Translation Layer for Executing Intel 8080 Assembler on a Quantum Computer (August 2022)
کیت توسعه نرم افزار و لایه ترجمه برای اجرای اسمبلر اینتل 8080 در رایانه کوانتومی (اوت 2022)-2022 One of the major obstacles to the adoption of quantum computing is the requirement to define
quantum circuits at the quantum gate level. Many programmers are familiar with high-level or low-level
programming languages but not quantum gates nor the low-level quantum logic required to derive useful
results from quantum computers. The steep learning curve involved when progressing from quantum gates to
complex simulations such as Shor’s algorithm has proven too much for many developers. The purpose of this
article and the software presented within addresses this challenge by providing a Software Development Kit
(SDK), translation layer, emulator, and a framework of techniques for executing Intel 8080/Z80 assembler on
a quantum computer, i.e., all salient points of CPU execution, logic, arithmetic, and bitwise manipulation will
be executed on the quantum computer using quantum circuits. This provides a novel means of displaying
the equivalency and interoperability of quantum and classical computers. Developers and researchers can
use the SDK to write code in Intel 8080/Z80 assembler which is executed locally via traditional emulation
and remotely on a quantum computer in parallel. The emulator features side-by-side code execution with
visibility of the running quantum circuit and reusable/overridable methods. This enables programmers to
learn, reuse, and contrast techniques for performing any traditional CPU-based technique/instruction on a
quantum computer, e.g., a programmer may know how to multiply and perform checks on a classical CPU
but is not able to perform the same tasks in a quantum implementation, and this SDK allows the programmer
to pick and choose the methods they would like to use to fulfil their requirements. The SDK makes use of
open-source software, specifically Python and Qiskit for the emulation, translation, API calls, and execution
of user-supplied code or binaries.

Data, data flows, and model specifications for linking multi-level contribution margin accounting with multi-level fixed-charge problems
دادهها، جریانهای داده، و مشخصات مدل برای پیوند حسابداری حاشیه سهم چندسطحی با مشکلات شارژ ثابت چندسطحی-2021 This article describes the data, data flows, and spreadsheet
implementations for linking multi-level contribution margin
accounting as a subsystem in cost accounting with several
versions of a multi-level fixed-charge problem (MLFCP), the
latter based on the optimization approach in operations research. This linkage can reveal previously hidden optimization potentials within the framework of multi-level contribution margin accounting, thus providing better information for decision making in companies and other organizations. For the data, plausible fictitious values have been assumed taking into consideration the calculation principles
in cost accounting where applicable. They include resourcerelated data, market-related data, and data from cost accounting needed to analyze the profitability of a companys´
products and organizational entities in the presence of hierarchically structured fixed costs. The data are processed and
analyzed by means of mathematical optimization techniques
and sensitivity analysis. The linkage between multi-level contribution margin accounting and MLFCP is implemented in
three spreadsheet files, including versions for deterministic
optimization, stochastic optimization, and robust optimization. This paper provides specifications for compatible solver
add-ins and for executing sensitivity analysis. The data and spreadsheet implementations described in this article were
used in a research article entitled “Making better decisions
by applying mathematical optimization to cost accounting:
An advanced approach to multi-level contribution margin accounting” [1]. The data sets and the spreadsheet implementations may be reused a) by researchers in management and
cost accounting as well as in operations research and quantitative methods for verification and for further development
of the linkage concept and of the underlying optimization
models; b) by practitioners for gaining insight into the data
requirements, methods, and benefits of the proposed linkage,
thus supporting continuing education; and c) by instructors
in academia who may find the data and spreadsheets valuable for classroom use in advanced courses. The complete
spreadsheet implementations in the form of three ready-touse Excel files (deterministic, stochastic, and robust version)
are available for download at Mendeley Data. They may serve
as customizable templates for various use cases in research,
practice, and education.

Knowledge reuse for ontology modelling in Maintenance and Industrial Asset Management
استفاده از دانش برای مدل سازی هستی شناسی در مدیریت نگهداری و مدیریت دارایی صنعتی-2021 Maintenance and Industrial Asset Management (AM) are fundamental business processes in guaranteeing the
availability of physical assets at minimum risk and cost, while balancing the interests of several stakeholders. To
reach operational excellence, intra- and inter-enterprise interoperability of systems is needed to support infor-
mation management and integration between several involved parties. To this end, ontology engineering is
relevant since it supports interoperability at technical and semantic levels. However, ontology modelling
methodologies are varied, and several best practices exist, amongst which knowledge reuse. Nevertheless,
reusing extant knowledge is not completely exploited so far, causing a heterogeneous ensemble of ontologies that
are not orchestrated. The present work aims at promoting the adoption of knowledge reuse for ontology
modelling in maintenance and AM. Therefore, an extensive review of existing ontologies for the two targeted
business processes is performed with a twofold objective: firstly, to realise a cross-industrial ontological com-
pendium, and secondly to understand the state of art of ontology modelling in maintenance and AM. To support
the adoption of knowledge reuse, this practice is framed in AMODO (Asset Management Ontology Development
methOdology). Finally, a laboratory-sized showcase is provided to prove the usefulness of relying on knowledge
reuse during the ontology development. The results show that the developed ontology is realised faster and is
inherently aligned with established ontologies, towards enterprise systems interoperability. Consequently,
maintenance and AM business processes may rely on information management and integration to pursue
operational excellence. keywords: هستی شناسی | استفاده مجدد از دانش | قابلیت همکاری | نگهداری | مدیریت دارایی | Ontology | Knowledge reuse | Interoperability | Maintenance | Asset management |

Reimagining the milk supply chain: Reusable vessels for bulk delivery
Reimagining زنجیره تامین شیر: ظروف قابل استفاده مجدد برای تحویل به صورت عمده-2021 Milk packaging has been analysed multiple times in pursuit of finding the most appropriate vessel from an environmental point of view. Research has concentrated on commercially available containers of 0.5 –2.5 litres, usually made from High-Density Polyethylene (HDPE), Polyethylene Terephthalate (PET), paper- based cartons, or glass, with some studies considering a reuse scheme for glass bottles. Whilst applicable for household delivery, such a reuse scheme is not practical for delivery to cafés where large volumes of milk are used every day; little information is known about transportation of bulk volumes of milk in bigger vessels such as steel churns. This study compares a proposed milk supply chain using a mix of reusable stainless steel churns and reusable glass bottles with the current supply chain that uses single- use HDPE bottles, for transportation of milk to 10 cafés belonging to The University of Sheffield. A cradle- to-grave life cycle assessment (LCA) is conducted using data obtained from the university and Our Cow Molly, a local dairy farm which delivers milk to the university. Sensitivity analysis was performed around the recycling rate of plastic bottles, water consumption for churn cleaning, the reuse rate of glass bottles and churns and the source of the on-farm electricity. The study suggests that the greenhouse gas emission can be lowered by approx. 6.5 tons of CO2 equivalent annually if the reuse scheme is applied (this equates to a 65% reduction for the processes analysed). Considerable savings are also reported in cate- gories such as water consumption, fossil resources depletion and cumulative energy demand. The reuse scheme is, however, likely to induce a similar or higher mineral resource use and higher environmental damage in the marine eutrophication category due to water treatment. Production of plastic bottles in the plastic scenario and maintenance and transport on the reusable side are the main contributors to the environmental impact. Further improvements in the reuse scenario could be achieved by reducing the amount of water used for cleaning and hence the electricity demand for water heating. The reuse scheme could also benefit environmentally from using an electric refrigerated van instead of a diesel vehicle.© 2021 Institution of Chemical Engineers. Published by Elsevier B.V.

Impact of information hiding on circular food supply chains in business-to-business context
تأثیر مخفی کردن اطلاعات بر روی زنجیره های تأمین مواد غذایی دایره ای در زمینه کسب و کار به تجارت-2021 This study has analyzed food supply chains from the circular economy viewpoint with a focus on knowledge hiding. In this paper, we examine the practice of hiding knowledge among stakeholders, in which dimension, what this knowledge is and whether there are differences among specific groups of stakeholders. This is applied to distributors, producers, consumers, retailers, suppliers and farmers working within the meat industry in Turkey. It shows how information hiding affects the traceability of food supply chains and circularity in the meat industry. Three different theories have been examined in this paper. Stakeholder theory helps to analyze traceability of food supply chains among stakeholders; the theory of industrial symbiosis aims to achieve an efficient circular food supply chain through 9R (refuse, rethink, reduce, reuse, repair, refurbish, remanufacture, repurpose, recycle, recover) strategies by adopting traceability; the information theory is a key enabler to co- ordinate traceability from farm to fork to support a circular food supply chain. By using the theoretical lens, this paper sets out proposals for policymakers and managers in food supply chains to ensure traceability and transparency to achieve circular economy. Although some prior studies address knowledge hiding, information hiding hasn’t been examined with traceability and transparency dimensions in Circular Food Supply Chain(CFSC) in B2B business. This study attempts to fill this gap in the literature, improve theoretical understanding with our proposed framework and validating the impact of information hiding and reveal where knowledge is mostly hidden in terms of circular economy, stakeholders and 9Rs in the meat industry. A proposed framework for managers and policymakers based on a circular economy can bring social, economic and environmental benefits for the red meat industry in Turkey. Additionally, it offers a framework and recommendations for other countries and industries for possible adoption.

Beyond blue: An extended framework of blue water footprint accounting
فراتر از آبی: یک چارچوب گسترده ای از حسابداری آبی آب آبی-2021 The water use of societies results in multiple environmental and social impacts and is a fundamental component
of sustainability. Correspondingly, water footprint studies have grown significantly in numbers over the last decade. However, these studies mostly account for the human appropriation of freshwater resources, while
overlooking various alternative water resources. This paper responds to the growing need for a complete
water footprint accounting and presents an extended framework of the blue water footprint, comprised of
seven water types. A case study shows spatially-explicit and use-specific analysis of Israels diverse water system.
Israels freshwater use accounts for only 40% of its total water use. Desalinated seawater and reused wastewater
contribute 52% and 45% to the countrys municipal and agricultural water use, respectively. The “original” blue
water footprint assumes only freshwater use; thus, it overestimates the appropriation of natural water resources
by humans. The extended blue water footprint accounts for seawater, brackish water, runoff, and reused wastewater along with surface water and fresh groundwater. It, therefore, estimates the human water use more
accurately.
Alternative water types use has some adverse environmental and health impacts. These include high energy intensity due to desalination, soil salinization from brackish water irrigation, and human exposure to traces of pharmaceutical in drinking water due to treated wastewater irrigation. By acknowledging the water mix of different sectors and regions, the extended blue water footprint contributes to advancing a water-energy nexus analysis or accounting for various environmental and health impacts of water use. keywords: دفع آب | مخلوط آب | تعاملات انسانی محیط زیست | Water-footprint | Water-mix | Human-environment-interactions |

Improving the sustainability of a reverse supply chain system under demand uncertainty by using postponement strategies
بهبود پایداری سیستم زنجیره تأمین معکوس تحت عدم اطمینان تقاضا با استفاده از استراتژی های به تعویق انداختن-2021 In recent decades, issues of resource depletion and waste piling have grown at an alarming rate, which are happening in the cases of product wastes with significant residual values, such as e-waste. To address these issues, stakeholders have focused to develop a reverse supply chain (RSC) system that can sustain profitable takeback, reuse, and recycling operations in the long-term. Such a system requires efficiency in handling complex operations involving various players while being responsive to demand uncertainty and changes. One way in realizing these capabilities is by incorporating postponement concepts to the integrated RSC network, allowing the delay of operations susceptible to demand uncertainty. This study pioneers the formulation of a two-stage stochastic mixed-integer model of a multi-player RSC with speculation-postponement strategies. The sample average approximation method is used to solve and verify the proposed model that has an uncertain demand. Various speculation-postponement strategies, namely, disassembly, reconditioning, and reassembly strategies are developed to configure forecast and demand-driven RSC operations, including the purchasing, product takeback, production planning, inven- tory, and item speculation decisions. Numerical examples of the notebook computer RSC demonstrate that utilizing the right operation postponement can increase the network’s flexibility, allowing better economic performances even under high demand uncertainty risks and stricter environmental regula- tions. In various cases, the RSC performs better with speculation-postponement strategies than without postponement strategy, demonstrating the proposed model’s superiority. This study can provide insight to decision-makers to improve RSC sustainability through postponement. Moreover, the model is generic and can be applied to other products as well.© 2021 Elsevier Ltd.

Intelligent decision-making of online shopping behavior based on internet of things
تصمیم گیری هوشمندانه از رفتار خرید آنلاین مبتنی بر اینترنت اشیا-2020 The development of big data and Internet of things (IoT) have brought big changes to e-commerce. Different
kinds of information sources have improved the consumers’ online shopping performance and make it possible to
realize the business intelligence. Grip force and eye-tracking sensors are applied to consumers online reviews
search behavior by relating them to the research approaches in IoT. To begin with, public cognition of human
contact degrees of recycled water reuses with grip force test was measured. According to the human contact
degrees, 9 recycled water reuses presented by the experiment are classified into 4 categories. Based on the
conclusion drawn from grip force test, purified recycled water and fresh vegetable irrigated with recycled water
are regarded as the drinking for high-level human contact degree and the irrigation of food crops for low-level
human contact degree respectively. Several pictures are designed for eye-tracking test by simulating an on-line
shopping web page on Taobao (the most popular online shopping platform in China). By comparing the fixation
time participants spent on the areas of interest (AOIs), we justify that consumers online reviews search behavior
is substantially affected by human contact degrees of recycled products. It was found that consumers rely on
safety perception reviews when buying high contact goods. Keywords: Online reviews search behavior | Recycled products | Grip force sensor | Eye-tracking sensor | Internet of Things (IoT) |
