Fast and reconfigurable packet classification engine in FPGA-based firewall

Abstract: In data communication via internet, security is becoming one of the most influential aspects. One way to support it is by classifying and filtering ethernet packets within network devices. Packet classification is a fundamental task for network devices such as routers, firewalls, and intrusion detection systems. In this paper we present architecture of fast and reconfigurable Packet Classification Engine (PCE). This engine is used in FPGA-based firewall. Our PCE inspects multi-dimensional field of packet header sequentially based on tree-based algorithm. This algorithm simplifies overall system to a lower scale and leads to a more secure system. The PCE works with an adaptation of single cycle processor architecture in the system. Ethernet packet is examined with PCE based on Source IP Address, Destination IP Address, Source Port, Destination Port, and Protocol fields of the packet header. These are basic fields to know whether it is a dangerous or normal packet before inspecting the content. Using implementation of tree-based algorithm in the architecture, firewall rules are rebuilt into 24-bit sub-rules which are read as processor instruction in the inspection process. The inspection process is comparing one sub-rule with input field of header every clock cycle. The proposed PCE shows 91 MHz clock frequency in Cyclone II EP2C70F896C6 with 13 clocks throughput average from input to output generation. The use of tree-based algorithm simplifies the multidimensional packet inspection and gives us reconfigurable as well as scalable system. The architecture is fast, reliable, and adaptable and also can maximize the advantages of the algorithm very well. Although the PCE has high frequency and little amount of clock, filtering speed of a firewall also depends on the other components, such as packet FIFO buffer. Fast and reliable FIFO buffer is needed to support the PCE. This PCE also is not completed with rule update mechanism yet. This proposed PCE is tested as a component of FPGA-based firewall to filter Ethernet packet with FPGA DE2 Board using NIOS II platform.

Are you listening to how I look? An exploration of the impact of emotional labour on educator effectiveness in higher education.

Abstract: A publication that has been cited in excess of three thousand times cannot fail to capture attention. Three decades on from the identification of a new form of labour by Hochschild and there is still much to explore with regard to emotional labour. Recent publications of literature concerning emotional labour have all helped to fill a gap left by the neglect of the impact of emotional labour on educator effectiveness in higher education. The purpose of emotional labour is to promote in others a feeling of being cared for. This paper will add to the topic by exploring the role and value of emotional labour with respect to lecturers in higher education. This objective is addressed by the author reflecting on her experience of 20 years employed in higher education predominantly in Ireland and is complimented by an analysis of the literature. It will identify types of emotional labour and emotional labour strategies within an Irish context. It will also examine the managerial implications of emotional labour and its impact on educator effectiveness. A related line of inquiry in the paper is the inclusion of aesthetic labour as an emotional labour strategy. To date aesthetic labour has been researched in isolation. This paper is unique in evaluating aesthetic labour along with the more widely researched forms of emotional labour in the context of educator effectiveness in higher education.

Profile Komposisi Tubuh Atlet Junior Bulutangkis Indonesia: Kategori Ganda Putra

Abstract: Penelitian ini bertujuan untuk mengukur karakteristik fisiologi, secara spesifik pada pengukuran antropometri, untuk mendapatkan gambaran somatotype atlet bulutangkis Indonesia. 12 atlet bulutangkis junior kategori ganda putra berpartisipasi dalam penelitian ini. Pengukuran antropometri dengan menggunakan alat GE Lunar Prodigy DEXA, dan stadiometer portable dengan keakuratan 0.1cm untuk mengukur tinggi badan. Rata-rata berat badan adalah 69.01 ± 7.55 kg , rata-rata tinggi badan adalah 175.3 ± 5.96 cm, rata-rata BMI adalah 22.43 ± 1.98 kg/ m-2 , rata-rata lemak adalah 13.02 ± 3.80 kg, rata-rata prosentase lemak adalah 19.49 ± 4.37%, rata-rata massa otot adalah 53.09 ± 5.28 kg, rata-rata massa otot adalah 74.40 ± 10.28 %, rata-rata rasio lemak android/genoid adalah 0.76 ± 0.19 %, rata-rata massa otot lengan atas kanan adalah 3.36 ± 0.43 Kg, rata-rata massa otot lengan atas kiri adalah 2.89 ± 0.52 Kg, rata-rata massa otot tungkai bawah kanan adalah 9.87 ± 1.26 Kg, dan rata-rata massa otot tungkai bawah kiri adalah 9.43 ± 1.37 Kg. Penelitian ini menunjukkan bahwa jenis somatotype tubuh atlet bulutangkis junior kategori ganda putra Indonesia adalah mesomorph . Hal ini diperjelas dengan rata-rata BMI atlet bulutangkis junior kategori ganda putra Indonesia yang berada pada rata-rata 22.43±1.98 kg/m-2.

Modality in RRG

Abstract: In this paper we are concerned with providing elements of a characterisation of modality in RRG using data from Irish, a VSO language found on the west of Europe We outline the characteristics of modality drawing on previous work on modality and modal logic, and relate this to patterns in sentence syntax and the semantics of the event frame Issues of scope and negation are examined and presented We extend the logical structure notation used in RRG (Van Valin 2005) to include additional logical notation to represent the modality expressions Deontic modality is concerned with obligation and permission whereas epistemic modality is concerned with knowledge and belief Modality is also concerned with coding of necessity versus possibility and, in some accounts, with the idea of “possible worlds” (Portner 2005) We motivate a relationship formally between deontic, dynamic and epistemic modality in terms of RRG A characterisation of modality in Irish is also provided
